“…As shown in Fig. 3, the lines calculated by JAM model are compared to the preliminary results from central Au+Au collisions at RHIC BES energies ( √ s NN = 7.7 to 200 GeV) measured by the STAR experiment [11,12]. For t/d ratio, we find the results from JAM model are in agreement with the data measured by STAR.…”

In relativistic heavy-ion collisions, the light nuclei production is sensitive to the baryon density fluctuations and can be used to probe the QCD phase transition. Based on the coalescence production of light nuclei, we can extract the neutron density fluctuation from the yield ratio of proton (p), deuteron (d) and triton (t), Np × Nt/N 2 d . In this work, we studied the production of proton, deuteron, triton in Au+Au collisions at √200 GeV from a transport model (JAM model). We presented the energy dependence of rapidity density dN/dy, particle ratios (d/p, t/p, and t/d), and the yield ratio of Np × Nt/N 2 d . We found the energy dependence of the yield ratio is flat and cannot describe the non-monotonic trend observed by STAR experiment. This study can be used as a baseline to search for the QCD critical point and/or first order phase transition with light nuclei production in heavy-ion collisions.

Transverse momentum spectra of π+, p, Λ, Ξ or Ξ¯+, Ω or Ω¯+ and deuteron (d) in different centrality intervals in nucleus–nucleus collisions at the center of mass energy are analyzed by the blast wave model with Boltzmann Gibbs statistics. We extracted the kinetic freezeout temperature, transverse flow velocity and kinetic freezeout volume from the transverse momentum spectra of the particles. It is observed that the non-strange and strange (multi-strange) particles freezeout separately due to different reaction cross-sections. While the freezeout volume and transverse flow velocity are mass dependent, they decrease with the resting mass of the particles. The present work reveals the scenario of a double kinetic freezeout in nucleus–nucleus collisions. Furthermore, the kinetic freezeout temperature and freezeout volume are larger in central collisions than peripheral collisions. However, the transverse flow velocity remains almost unchanged from central to peripheral collisions.

Transverse momentum spectra of +, p, Λ, Ξ or ¯Ξ+, Ω or ¯Ω+ and deuteron (d) in different centrality intervals in Gold-Gold (Au-Au) and Lead-Lead (Pb-Pb) collisions at 62.4 GeV and 2.76 TeV respectively, are analyzed by the blast wave model with Boltzmann Gibbs statistics. We extracted Kinetic freeze out temperature,transverse flow velocity and kinetic freezeout volume from the transverse momentum spectra of the particles. It is observed that the non-strange and strange (multi-strange) particles freezeout separately due to different reaction cross-sections. While the freezeout volume and transverse flow velocity are mass dependent which decrease with the rest mass of the particles. The present work reveals the scenario of double kinetic freezeout in collisions at STAR and ALICE Collaborations. Furthermore, the kinetic freezeout temperature and freezeout volume are larger in central collisions than the peripheral collisions and they decrease from central to periphery. However the transverse flow velocity remains almost unchanged from central to peripheral collisions.
