标题： Freeze-out conditions for production of resonances, hadronic molecules, and light nuclei

摘要： 我们研究在相互作用粒子的膨胀系统中粒子的冻结条件，以了解重离子碰撞中共振态、强子分子和轻核的产生。 将动量冻结条件与膨胀强子相的显式流体力学计算应用于$K^*$介子的子粒子，我们发现与基于化学冻结参数的统计强子化模型的预期相比，LHC 中$K^*/K$的产率比在 RHIC 中的抑制更大，这反映了 LHC 的动量冻结温度低于 RHIC。 此外，我们指出对于结合的轻核或强子分子，其产率受强子物质中相应粒子的冻结条件影响，这导致观察到氘核的产率与氘核的大小无关，仅取决于基态组分的数量。 显示英文摘要

摘要： We investigate the freeze-out conditions of a particle in an expanding system of interacting particles in order to understand the productions of resonances, hadronic molecules and light nuclei in heavy ion collisions. Applying the kinetic freeze-out condition with explicit hydrodynamic calculations for the expanding hadronic phase to the daughter particles of $K^*$ mesons, we find that the larger suppression of the yield ratio of $K^*/K$ at LHC than at RHIC compared to the expectations from the statistical hadronization model based on chemical freeze-out parameters reflects the lower kinetic freeze-out temperature at LHC than at RHIC. Furthermore, we point out that for the light nuclei or hadronic molecules that are bound, the yields are affected by the freeze-out condition of the respective particle in the hadronic matter, which leads to the observation that the deuteron production yields are independent of the size of deuteron, and depend only on the number of ground state constituents.
