Measurement of ψ(2S) nuclear modification at backward and forward rapidity in p+p, p+Al, and p+Au collisions at sNN=200 GeV

In relativistic heavy-ion collisions, the analysis of charmonium yields normalized to those in pp collisions has been shown to reveal final-state interactions occurring in the hot and dense strongly interacting matter created in such events. However, until recently, similar analyses of charmonium measured in smaller collision systems—pA versus pp—were performed in terms of cold nuclear matter effects. The measurements reported by the PHENIX Collaboration of the production of J/Ψ and Ψ(2S) states at forward and backward rapidity, strongly suggest the presence of final-state effects also in small collision systems.

Transient Joule- and (ac) Josephson-like photon emission in one- and two- nucleon tunneling processes between superfluid nuclei: Blackbody and coherent spectral functions

In analogy with the phenomena occurring when two superconductors are placed in proximity, effectively charged neutrons involved in one- and two-nucleon tunneling processes in heavy-ion collisions between superfluid nuclei are expected to emit photons. Based on T-matrix calculations, a quantal coherent, or AC Josephson-like, character of the emission is predicted in the case of the Cooper-pair transfer (a two-nucleon channel), whereas a thermally equilibrated (Joule-like) character is obtained for the quasiparticle (one-nucleon channel) transfer. These findings provide a new microscopic insight into superfluidity in finite quantum systems and may stimulate new experimental analyses.

Nuclear coherent population transfer to the Th229m isomer using x-ray pulses

Pumping electrons in atoms via a gateway state to metastable states is a common and important tool with many applications, but the same process has yet to be achieved in atomic nuclei. The authors provide detailed mechanisms to pump a metastable state of 229Th at the extraordinarily low nuclear excitation energy of 8 eV, while also pointing out important gaps in our knowledge of this system. A population inversion to this state could be the basis for a novel “nuclear clock” to rival atomic clocks.

Impact of fragment formation on shear viscosity in the nuclear liquid-gas phase transition region

The dimensionless ratio of shear viscosity to entropy density η/s typically has a minimum at a phase transition as observed in many atomic and molecular systems. This quantity has been under intense study in high-energy heavy-ion collisions as a sign of a QCD phase transition or rapid crossover between hadronic and quark-gluon degrees of freedom. The authors perform numerical simulations of matter at lower density and temperature associated with a minimum in η/s which may shed light on the nuclear liquid-gas phase transition and its connection to the QCD transition.

Search for electron-neutrino transitions to sterile states in the BEST experiment

First results from the BEST Collaboration searching for short-baseline neutrino oscillations to sterile neutrinos with a high-intensity 51Cr monoenergetic neutrino source reaffirm that the so-called gallium anomaly, a deficit in electron neutrinos, persists. 4σ deficits were observed in the 71Ge production rates at two different distance scales, which could be interpreted as oscillations between an electron neutrino and a hypothetical sterile neutrino. The results are consistent with oscillations with a mass squared difference above about 0.5 eV2 and a large mixing angle sin22θ0.4.

New narrow resonances observed in the unbound nucleus F15

The unbound nucleus 15F was studied in proton-induced reactions on 14O, producing three narrow resonances above the 2p decay threshold in 15F. In comparison to calculations that account for the particle continuum, it was found that the properties of these resonances are determined by the proximity to proton decay channels rather than by carrying the imprint of 14O(0+)+1p configurations. Systematic investigations of such narrow resonances in unstable nuclei will open new perspectives in studies of effective interactions in nuclear open quantum systems.
