Abstract
Based on nucleons () and hyperons () formed at kinetic freeze-out from a quark combination model, we systematically study the production of light nuclei and hypernuclei in the hadronic coalescence picture. We present the analytical formula of the nucleus momentum distribution of two-body coalescence and that of three-body coalescence. We explain the experimental data of the transverse momentum spectra of deuteron (), triton (), helium-3 (), and hypertriton () measured in Au-Au collisions from the RHIC Beam Energy Scans I and II, and also provide the corresponding predictions of different hypernuclei , and . We further study the production correlations of different species of light (hyper-)nuclei and discuss their interesting behaviors as a function of collision energy.
