Background: In the production of hot quark gluon plasma in high-energy heavy-ion collisions, the charmonium binding in the deconfined interior is prevented by color screening. The formation of deconfining plasma was found as a signature of reduction of the charmonium (a bound state of charm and anticharm quark) production. A significant amount of charm suppression has been observed in heavy-ion collisions $\left(p\text{−}A\right)$ in various experimental investigations. Some of the issues are still not clear in this area of research, such as the study of hadronic properties in dense nuclear matter, the deconfinement phase transition from hadronic to quark gluon matter, etc. We follow up on the recently published work of Jamal et al. [M. Y. Jamal, I. Nilima, V. Chandra, and V. K. Agotiya, Phys. Rev. D 97, 094033 (2018)]; in this work the authors calculated the properties of quarkonia [i.e., potential, binding energy, and dissociation temperature (using thermal width criteria)] in the presence of temperature and anisotropy.

Purpose: To investigate the properties of quarkonia, namely, potential, binding energy, mass spectra, dissociation temperature (using thermal width and thermal energy criteria), and thermodynamical properties of quark gluon plasma (i.e., pressure, energy density, and speed of sound) in the presence of baryonic chemical potential $\left({\mu }_b\right)$ and anisotropy $\left(\xi \right)$.

Methods: The properties of quarkonia and the thermodynamical properties of quark gluon plasma (QGP) are calculated by using the quasiparticle approach with ${\mu }_b$ in hot quantum chromodynamics medium. The medium modified form of heavy-quark potential at finite values of ${\mu }_b$ and $\xi$ is considered. The calculations have been done by considering the real and imaginary parts of the potential with a static gluon propagator. The real part of the potential has been used in solving the Schrödinger equation to obtain the binding energy of quarkonia, and the imaginary part gives rise to the thermal width of heavy quarkonia.

Results: The binding energy and the dissociation temperature of $S$ states of charmonia and bottomonia for $n=1$ and $n=2$ (radial quantum number) and the mass spectra of $1S$ states of quarkonia with the effects of ${\mu }_b$ and $\xi$ were calculated. The thermodynamical properties of QGP using the parameters $\xi$ and ${\mu }_b$ were also determined. It was noticed that, with an increase in the value of ${\mu }_b$, the values of the associated properties of quarkonia decrease. On the other hand, by increasing the value of $\xi$, the values of the properties of quarkonia increase. The extracted values of mass spectra and the variation of thermodynamical properties of QGP are also compared with the recently published theoretical and experimental data and a reasonable agreement between these values is observed.

Conclusions: We have studied the properties of quarkonium state (i.e., $1S$ and $2S$-states) and the thermodynamical properties of QGP with ${\mu }_b$ and $\xi$ in hot and dense quantum chromodynamics medium. Finally with this, we may conclude that the obtained result (mention in result section) might be helpful for enhancing studies of the highly dense object (because Compressed Baryonic Matter experiment at the Facility for Anti-proton and ion Research in exploring QGP at higher baryon densities).

The atomic mass of uranium-238 has been determined to be $238.050787618\left(15\right)$ u, improving the literature uncertainty by two orders of magnitude. It is obtained from a measurement of the mass ratio of ${}^{238}\mathrm{U}^{47+}$ and ${}^{132}\mathrm{Xe}^{26+}$ ions with an uncertainty of $3.5\times {10}^{-12}$. The measurement was carried out with the Penning-trap mass spectrometer Pentatrap and was accompanied by a calculation of the binding energies $E_{\text{U}}$ and $E_{\text{Xe}}$ of the 47 and 26 missing electrons of the two highly charged ions, respectively. These binding energies were determined using an ab initio multiconfiguration Dirac-Hartree-Fock method to be $E_{\text{U}}=39927\left(10\right)$ eV and $E_{\text{Xe}}=8971.2\left(21\right)$ eV. The new mass value will serve as a reference for high-precision mass measurements in the heavy mass region of the nuclear chart up to transuranium nuclides.

We performed a measurement of the ${}^{51}\mathrm{V}(d,p){}^{52}\mathrm{V}$ reaction at 16 MeV using the Florida State University Super-Enge Split-Pole Spectrograph (SE-SPS) to search for single-neutron transfer strength for the $g_{9/2}$ intruder orbit. Measurements of $\nu g_{9/2}$ strength with ($d,p$) reactions in the $N=29$ isotones ${}^{49}\mathrm{Ca}, {}^{51}\mathrm{Ti}, {}^{53}\mathrm{Cr}$, and ${}^{55}\mathrm{Fe}$ have concluded that much of the expected $\nu g_{9/2}$ strength is “missing”; that is, the summed strength is much smaller than the sum rule. In odd-odd $N=29$ isotones, we expect a significant amount of $\nu g_{9/2}$ strength to be located in the “stretched” $8^{-}$ states with $\pi f_{7/2}^n\nu g_{9/2}$ structure that were systematically observed in the odd-odd $N=29$ isotones via the $(\alpha ,d)$ reaction. ${}^{52}\mathrm{V}$ is the only one of these odd-odd isotones in which a stable target is available for single-neutron transfer reactions. We report on a determination of $\nu g_{9/2}$ strength for the stretched $8^{-}$ state and ten other negative parity states populated via $L=4$ transfer in the ${}^{51}\mathrm{V}(d,p){}^{52}\mathrm{V}$ reaction. This is the first measurement of spectroscopic strength for $L=4$ states in ${}^{52}\mathrm{V}$ via ($d,p$). In total, the $L=4$ strength observed here sums to only $28.9\left(11\right)\%$ of the sum rule for $g_{9/2}$ neutron strength, a result that is consistent with the summed strengths observed in recent ($d,p$) measurements of the even-Z $N=29$ isotones ${}^{51}\mathrm{Ti}, {}^{53}\mathrm{Cr}$, and ${}^{55}\mathrm{Fe}$. The $\left(\alpha {,}^3\mathrm{He}\right)$ reaction and the use of particle-$\gamma$ coincidences would provide more sensitivity to search for the missing $g_{9/2}$ strength.

The accurate determination of the nuclear interaction potential is essential for predicting fusion cross sections and understanding the reaction mechanism, which plays an important role in the synthesis of superheavy elements. In this work, a neural network, which combines with the calculations of the fusion cross sections via the Hill-Wheeler formula, is developed to optimize the parameters of the Woods-Saxon potential by comparing the experimental values. The correlations between the parameters of Woods-Saxon potential and the reaction partners, which can be quantitatively fitted to a sigmoid-like function with the mass numbers, have been displayed manifestly for the first time. This study could promote the accurate estimation of the nucleus-nucleus interaction potential in low energy heavy-ion collisions.

The fission process of the excited compound nucleus ${}^{240}\mathrm{Pu}$ produced in neutron-induced reactions at incident energies from thermal to 14 MeV has been simulated by using a stochastic approach based on four-dimensional Langevin equations. The fission cross section, the total kinetic energy of fission fragments, the mass distribution of fission fragments, the average prompt neutron multiplicity, the average spin of fission fragments, and the mean fission time have been calculated for the excited compound nucleus ${}^{240}\mathrm{Pu}$. Three collective shape coordinates plus the projection of total spin of the compound nucleus on the symmetry axis, $K$, were considered in the four-dimensional dynamical model. In the dynamical calculations the effect of the neck radius in the scission configuration on the total kinetic energy of fission fragments of the ${}^{240}\mathrm{Pu}$ nucleus was examined. In the dynamical calculations, nuclear dissipation was generated through the chaos weighted wall-and-window friction formula with a chaoticity coefficient $\mu$. In the calculations, the chaoticity coefficient was considered as a free parameter and its magnitude was inferred for ${}^{240}\mathrm{Pu}$ by fitting measured data on the fission cross section. It was shown that the results of calculations for the fission cross section are in good agreement with the experimental data by using the magnitude of the chaoticity coefficient $\mu =0.4$. Furthermore, by reproducing experimental data on the total kinetic energy of fission fragments for the excited compound nucleus ${}^{240}\mathrm{Pu}$, the magnitude of the neck radius at which rupture occurs was inferred. It was shown that the results of the total kinetic energy of fission fragments are very sensitive to the value of the neck radius at which rupture occurs. It was also shown that the results of calculations for the total kinetic energy of fission fragments for ${}^{240}\mathrm{Pu}$ are in good agreement with the experimental data by using the magnitude of the radius in the scission configuration equal to $2.2\mathrm{fm}$. Furthermore, the mass distribution of fission fragments and the average prompt neutron multiplicity have also been calculated for ${}^{240}\mathrm{Pu}$ by using these appropriate values for the chaoticity coefficient and the neck radius in the scission configuration. Comparison of the calculated data with the experimental data has shown that the results of calculations are in good agreement with the experimental data by using these appropriate values. Finally, the average spin of fission fragments and the mean fission time have also been calculated for ${}^{240}\mathrm{Pu}$. It was shown that the average spin of fission fragments is strongly mass dependent and has a sawtooth shape, and also the mean fission time decreases rapidly with increasing incident neutron energy.

We study the properties of baryons consisting of three heavy quarks (“triply heavy baryons”) in the vacuum and in a hot QCD medium, which is created in relativistic heavy-ion collisions. Masses and wave functions of ${\mathrm{\Omega }}_{ccc}, {\mathrm{\Omega }}_{ccb}, {\mathrm{\Omega }}_{bbc}$, and ${\mathrm{\Omega }}_{bbb}$ up to the second radial excited states are obtained by solving the three-body Schrödinger equation with the hyperspherical harmonics method. With parameters completely fixed by fitting quarkonium bound states in vacuum, we predicted the masses for $1S, 2S$, and $3S$ states of triply heavy baryons. We also computed the temperature dependence of baryon masses and the thermal widths in a hot QCD medium. These properties are important for the precise study of triply heavy baryon production in heavy ion collisions.

We explore the squeezed back-to-back correlation (SBBC) and investigate how the squeezing effect influences the Hanbury-Brown–Twiss (HBT) interferometry using an expanding Gaussian source with nonzero width. The SBBC and HBT of $D^0$ and $\varphi$ mesons with finite in-medium widths are studied. The expanding flow of the source may enhance the SBBC strength of $D^0{\overline{D}}^0$ and $\varphi \varphi$ in the low momentum region but suppress the SBBC in the larger momentum region. The squeezing effect suppresses the influence of flow on the HBT radii, which is significant for two identical bosons with large pair momentum or with large mass. Due to the squeezing effect, the relationship between the HBT radii and the pair momentum exhibits nonflow behavior for the $D^0{D}^0$ pair. Likewise, nonflow behavior also appears in the HBT radii of $\varphi \varphi$ with large pair momentum. This phenomenon may bring new insights for studying the squeezing effect.

The in-medium properties of open strange ($K$, $\overline{K}$), open charm ($D$, $\overline{D}$), and open bottom ($B$, $\overline{B}$) mesons are investigated in asymmetric nuclear matter using quark meson coupling (QMC) model. A direct coupling of scalar ($\sigma$, $\delta$) and vector ($\omega$, $\rho$) mesons to the light quarks and antiquarks of these mesons give rise to the in-medium modification of the properties of the corresponding meson within the model. The inclusion of the $\delta$ (scalar isovector) meson breaks the isospin symmetry for the masses of the light quark and antiquark doublets, causing mass splitting between ($u,d$) as well as ($\overline{d},\overline{u}$). Consequently, the considered mesons exhibit mass splittings within the isodoublets of $K$, $\overline{K}$, $D$, $\overline{D}$, $B$, and $\overline{B}$ mesons when embedded in asymmetric nuclear matter. In the current study, the interactions of the pseudoscalar meson with the scalar, as well as vector mesons, are considered, which lead to significant medium modifications of the excitation energies of the open strange (charm and bottom) mesons. In asymmetric nuclear matter, due to the interaction of the pseudoscalar meson with the vector isovector $\rho$ meson, there is a splitting in the excitation energies of the mesons within the isospin doublets. The isospin effects are seen to be large for high baryon densities. This study can have significant observable consequences, such as in the production ratios, e.g., $K^{+}/K^0$, $K^{-}/{\overline{K}}^0$, $D^{+}/D^0$, $D^{-}/{\overline{D}}^0$, $B^{+}/B^0$, and $B^{-}/{\overline{B}}^0$ in the upcoming heavy ion collision experiments at the FAIR project at GSI, where the experiments are planned to be performed using neutron-rich beams to study the compressed baryonic matter.

In this study, we calculate the nuclear matrix elements (NMEs) for the light neutrino-exchange mechanism of neutrinoless double beta decay ($0\nu \beta \beta$) of ${}^{124}\mathrm{Sn}$ within the framework of the interacting nuclear shell model, using the effective shell model Hamiltonian GCN5082. The NMEs are calculated employing both closure and nonclosure approaches. For the intermediate nucleus ${}^{124}\mathrm{Sb}$, effects of energy of 100 states for each $J_k^{\pi }=0^{+}$ to ${11}^{+}$ and $2^{-}$ to $9^{-}$ ($\mathrm{\Delta }{J}_k=1)$ are explicitly included in the nonclosure approach. The optimal closure energy, which reproduces nonclosure NMEs using the closure approach, is found to be $\approx$ 3 MeV for $0\nu \beta \beta$ decay of ${}^{124}\mathrm{Sn}$. The NMEs for $0\nu \beta \beta$ decay of ${}^{124}\mathrm{Sn}$ did not fully converge with 100 intermediate states for each spin-parity of ${}^{124}\mathrm{Sb}$. A comparison of NMEs and lower limits of $T_{1/2}^{0\nu }$ with some of the recent calculations is presented. Further, to gain a comprehensive understanding of the role of nuclear structure on the $0\nu \beta \beta$ decay, the dependence of NMEs on the spin-parity of the intermediate states, coupled spin-parity of neutrons and protons, and the number of intermediate states, is explored. The estimated lower limit on the half-life $T_{1/2}^{0\nu }\approx 7.49\times {10}^{26}$ yr provides valuable input for the experimental investigations of $0\nu \beta \beta$ decay of ${}^{124}\mathrm{Sn}$ in India and elsewhere.

Background: The ${}^9\mathrm{Be}$ neutron capture cross section has significant implications for Be materials in the nuclear industry as well as the α process in stellar nucleosynthesis. While the cross section is well constrained at thermal neutron energies, there is a lack of experimental data at higher neutron energies, and the evaluated nuclear data libraries can differ by up to two orders of magnitude.

Purpose: We calculate the ${}^9\mathrm{Be}(n,\gamma ){}^{10}\mathrm{Be}$ integral cross section at fission neutron energies in an effort to resolve disagreements amongst the nuclear data libraries.

Methods: Foil irradiation experiments were performed using the Flattop critical assembly at the National Criticality Experiments Research Center with either the highly enriched U or Pu cores, with target foil stacks placed at multiple locations to exploit different neutron energy profiles. Accelerator mass spectrometry was used to measure the ${}^{10}\mathrm{Be}/{}^9\mathrm{Be}$ ratio in irradiated Be foils, while all other activation products were quantified through gamma spectrometry. The experiments were simulated using the Monte Carlo $N$-Particle radiation transport code and combined with experimental results to determine the total neutron fluence, while the staysl-pnnl suite and fispact-ii code were used to validate the model and assess the systematic uncertainty.

Results: The new ${}^9\mathrm{Be}(n,\gamma ){}^{10}\mathrm{Be}$ integral cross sections calculated in this work are $26.5\pm 2.2\mu \mathrm{b}$ at $0.59\pm 0.07$ MeV, $24\pm 3\mu \mathrm{b}$ at $0.98\pm 0.14$ MeV, $21.7\pm 1.3\mu \mathrm{b}$ at $1.26\pm 0.11$ MeV, $21.8\pm 1.4\mu \mathrm{b}$ at $1.32\pm 0.11$ MeV, and $18.6\pm 1.1\mu \mathrm{b}$ at $1.46\pm 0.13$ MeV. These results do not agree with integral cross sections from any of the nuclear data library evaluations.

Conclusions: Discrepancies between the new integral cross sections reported here and the nuclear data libraries suggest a more complex cross-section structure in the MeV range which allows for more resonance contributions, and more work is needed to further constrain the evaluated cross sections.

We perform two-pion Hanbury-Brown–Twiss (HBT) interferometry for the partially coherent pion-emitting sources in relativistic heavy-ion collisions using a multiphase transport (AMPT) model. A longitudinal coherent emission length, as well as a transverse coherent emission length, are introduced to the pion generation coordinates in calculating the HBT correlation functions of the partially coherent sources. We compare the model results with and without coherent emission conditions with experimental data in Au-Au collisions at center-of-mass energy $\sqrt{s_{NN}}=200\mathrm{GeV}$ and in Pb-Pb collisions at center-of-mass energy $\sqrt{s_{NN}}=2.76\mathrm{TeV}$, and find that the HBT results of the partially coherent sources are closer to the experimental data than those of chaotic sources.

We present results of simulations of light-nuclei production in $\mathrm{Au}+\mathrm{Au}$ collisions at a collision energy of $\sqrt{s_{NN}}=3$ GeV within the updated Three-fluid Hydrodynamics-based Event Simulator Extended by UrQMD (ultrarelativistic quantum molecular dynamics) final State interactions (THESEUS). The results are compared with recent STAR data. The light-nuclei production is treated within the thermodynamical approach on an equal basis with hadrons. The only additional parameter related to the light nuclei is the energy density of late freeze-out that imitates the afterburner stage of the collision because the light nuclei do not participate in the UrQMD evolution. It is found that the late freeze-out is preferable for deuterons, tritons, and ${}^3\mathrm{He}$. Remarkably, the ${}^4\mathrm{He}$ observables are better reproduced with the standard freeze-out. This suggests that the ${}^4\mathrm{He}$ nuclei better survive in the afterburner stage because they are more spatially compact and tightly bound objects. This is an argument in favor of dynamical treatment of light nuclei. The simulations indicate that the collision dynamics is determined by the hadronic phase. The calculated results reveal a not perfect, but good reproduction of the data on bulk observables and directed flow. The elliptic flow turns out to be more intricate.

Background: The energy distribution of excited states populated by the nuclear muon capture reaction can facilitate an understanding of the reaction mechanism; however, experimental data are fairly sparse.

Purpose: We developed a novel method, called the in-beam activation method, to measure the production probability of residual nuclei by muon capture. For the first application of the new method, we have measured the muon-induced activation of five isotopically enriched palladium targets.

Methods: The experiment was conducted at the RIKEN-RAL muon facility of the Rutherford Appleton Laboratory in the UK. The pulsed muon beam impinged on the palladium targets, and $\gamma$ rays from the $\beta$ and isomeric decays from the reaction residues were measured using high-purity germanium detectors in both the in-beam and offline setups.

Results: The production branching ratios of the residual nuclei of muon capture for five palladium isotopes with mass numbers $A=104$, 105, 106, 108, and 110 were obtained. The results were compared with a model calculation using the particle and heavy ion transport system (phits) code. The model calculation well reproduces the experimental data.

Conclusion: For the first time, this study provides experimental data on the distribution of production branching ratios without any theoretical estimation or assumptions in the interpretation of the data analysis.

The angular distributions for the elastic scattering and breakup reactions of the mirror nuclei ${}^{12}\mathrm{B}$ and ${}^{12}\mathrm{N}$ on a ${}^{208}\mathrm{Pb}$ target, at incident energies of 255 MeV and 343 MeV, respectively, were measured at HIRFL-RIBLL. The elastic scattering and breakup angular distributions of the halolike nucleus ${}^{12}\mathrm{N}$ ($S_p=0.601$ MeV) have been measured simultaneously. Elastic scattering cross sections were accurately reproduced by continuum discretized coupled channel calculations, which did not exhibit any significant Coulomb rainbow suppression. We have analyzed the energy and angular distributions of inclusive ${}^{11}\mathrm{B}$ and ${}^{11}\mathrm{C}$ fragments, produced by direct reaction processes, taking into account the contributions from both elastic breakup (EBU) and nonelastic breakup (NEB). Since the breakup data is inclusive with respect to the final state of the core nucleus, the contribution of each of these core states was calculated separately and then the corresponding cross sections added together using as weights the spectroscopic factors for each configuration computed with the $\mathit{ab}$ initio no-core shell model. The results were found to be mostly consistent with the experimental data and, furthermore, demonstrate that EBU is highly dependent on the binding energy, while the results of NEB show no clear effect.

The first measurements of $K^{*}{\left(892\right)}^0$ resonance production as a function of charged-particle multiplicity in Xe-Xe collisions at $\sqrt{s_{NN}}=5.44$ TeV and $pp$ collisions $\text{at}\sqrt{s}=5.02$ TeV using the ALICE detector are presented. The resonance is reconstructed at midrapidity ($\left|\mathit{y}\right| <$ 0.5) using the hadronic decay channel $K^{*0} \to K^{\pm }{\pi }^{\mp }$. Measurements of transverse-momentum integrated yield, mean transverse-momentum, nuclear modification factor of $K^{*0}$, and yield ratios of resonance to stable hadron ($K^{*0}/K$) are compared across different collision systems ($pp, p$-Pb, Xe-Xe, and Pb-Pb) at similar collision energies to investigate how the production of $K^{*0}$ resonances depends on the size of the system formed in these collisions. The hadronic rescattering effect is found to be independent of the size of colliding systems and mainly driven by the produced charged-particle multiplicity, which is a proxy of the volume of produced matter at the chemical freeze-out. In addition, the production yields of $K^{*0}$ in Xe-Xe collisions are utilized to constrain the dependence of the kinetic freeze-out temperature on the system size using the hadron resonance gas–partial chemical equilibrium model.

Background: Recent measurements indicate that the previously established upper limit for the $\gamma$-decay branch of the $3_1^{-}$ resonance in ${}^{12}\mathrm{C}$ at $E_x=9.641\left(5\right)$ MeV may be incorrect. As a result, the $3_1^{-}$ resonance has been suggested as a significant resonance for mediating the triple-$\alpha$ reaction at high temperatures above 2 GK. Accurate estimations of the $3_1^{-}$ contribution to the triple-$\alpha$ reaction rate require accurate knowledge of not only the radiative width, but also the total width.

Purpose: In anticipation of future measurements to more accurately determine the $\gamma$-decay branch of the $3_1^{-}$ resonance, the objective of this work is to accurately determine the total width of the $3_1^{-}$ resonance.

Method: An evaluation was performed on all previous results considered in the current ENSDF average of 46(3) keV for the physical total width (FWHM) of the $3_1^{-}$ resonance in ${}^{12}\mathrm{C}$. A new $\mathbf{R}$-matrix analysis for the $3_1^{-}$ resonance was performed with a self-consistent, simultaneous fit of several high-resolution ${}^{12}\mathrm{C}$ excitation-energy spectra populated with direct reactions.

Results: The global analysis performed in this work yields a formal total width of $\mathrm{\Gamma }\left(E_r\right)=46\left(2\right)$ keV and an observed total width of ${\mathrm{\Gamma }}_{\text{obs}}\left(E_r\right)=38\left(2\right)$ keV for the $3_1^{-}$ resonance.

Conclusions: Significant unaccounted-for uncertainties and a misstated result were discovered in the previous results employed in the ENSDF for the physical (or observed) total width of the $3_1^{-}$ resonance. These previously reported widths are fundamentally different quantities, leading to an invalid ENSDF average. An observed total width of ${\mathrm{\Gamma }}_{\text{obs}}\left(E_r\right)=38\left(2\right)$ keV is recommended for the $3_1^{-}$ resonance in ${}^{12}\mathrm{C}$. This observed total width should be employed for future evaluations of the observed total radiative width for the $3_1^{-}$ resonance and its contribution to the high-temperature triple-$\alpha$ reaction rate.

Microscopic calculations of neutrino-nucleus scattering cross sections are critical for the success of the neutrino-oscillation program. In addition to retaining nuclear correlations in the initial and final state of the reaction, they are based on consistent nuclear interactions and transition current operators, thereby enabling robust uncertainty quantification. In this work, we address a significant limitation of these microscopic methods, which arises from their nonrelativistic nature. By performing the calculations in a reference frame that minimizes nucleon momenta and utilizing the so-called two-fragment model, we extend the applicability of Green's function Monte Carlo calculations of neutrino-nucleus scattering to higher momenta than currently possible. To validate this approach, we compare our theoretical predictions against inclusive data measured by the MiniBooNE, T2K, and $\mathrm{MINER}\nu \mathrm{A}$ experiments.

The multiplicity dependence of multistrange hadron yields in proton-proton and lead-lead collisions at several TeV allows one to study the transition from very big to very small systems, in particular, concerning collective effects. I investigate this, employing a core-corona approach based on new microcanonical hadronization procedures in the epos4 framework, as well as new methods allowing one to transform energy-momentum flow through freeze-out surfaces into invariant-mass elements. I try to disentangle effects due to “canonical suppression” and “core-corona separation”, which will both lead to a reduction of the yields at low multiplicity.

We investigate the weak-interaction-driven bulk-viscous transport properties of npe matter in the neutrino transparent regime. Previous works assumed that the induced bulk viscosity correction to pressure, near beta equilibrium, is linear in deviations from the equilibrium charge fraction. We show that this is not always true for (some) realistic equations of state at densities between one and three times saturation density. This nonlinear nature of the perturbation around equilibrium motivates a far-from-beta-equilibrium description of bulk-viscous transport in neutron star mergers, which can be precisely achieved using a new Israel-Stewart formulation with resummed bulk and relaxation time transport coefficients. The computation of these transport coefficients depends on out-of-beta-equilibrium pressure corrections, which can be computed for a given equation of state. We calculate these coefficients for equations of state that satisfy the latest constraints from multimessenger observations from LIGO/Virgo and NICER detectors. We show that varying the nuclear symmetry energy $J$ and its slope $L$ can significantly affect the transport coefficients and the nonlinear behavior of the out-of-equilibrium pressure corrections. Therefore, having better constraints on $J$ and $L$ will directly impact our understanding of bulk-viscous processes in neutron star mergers.
