摘要

分析了高能重离子碰撞中新核和超核的形成。我们使用了膨胀核物质中局部化学平衡的假说。在这封信中，超相对论量子分子动力学（UrQMD）、杜布纳级联模型（DCM）和统计多碎片模型（SMM）被应用于核子和超核子产生的理论计算。在我们的混合方法中获得了与实验数据的良好一致性。未来计划在 FAIR、NICA 和其他加速器上进行的实验将为研究原子核和热（超）物质提供极好的机会。

Dynamical and Statistical Simulations for the Production of Nuclei and Hypernuclei at High Energy Ion Collisions

The formation of new nuclei and hypernuclei in heavy-ion collisions at high energies is analysed. We use the hypothesis of local chemical equilibrium in expanding nuclear matter. In this letter, the ultra-relativistic quantum molecular dynamics (UrQMD), the Dubna cascade model (DCM), and statistical multifragmentation model (SMM) are applied for theoretical calculations of nuclei and hypernuclei production. Good agreement with experimental data is obtained within our hybrid approach. Experiments planned for the future at FAIR, NICA, and other accelerators will provide an excellent opportunity for study of nuclei and hot (hyper-)matter.
