论文摘要
我们介绍了用新型的强子共振气体模型获得的最新结果的摘要，该模型具有多组分硬核排斥，该模型扩展了以描述Hadrons和Light（Anti-tim-Hyper-）核的混合物。对于在碰撞能量$ \ sqrt {s_ {nn}} = 200 $ GEV和Alice At $ \ sqrt {s_ {s_ {nn}} = 2.76 $ tev的情况下，通过恒星在碰撞能量$ \ sqrt {s_ {nn}} = 200 $ GEV处测量的辐射核数据非常准确的描述。这里讨论的最引人注目的结果是，对于最可能的化学冻结场景，发现的参数使我们能够重现实验比的值$ s_3 $和$ \ overline {s} _3 $而无需安装。
We present a summary of the recent results obtained with the novel hadron resonance gas model with the multicomponent hard-core repulsion which is extended to describe the mixtures of hadrons and light (anti-, hyper-)nuclei. A very accurate description is obtained for the hadronic and the light nuclei data measured by STAR at the collision energy $\sqrt{s_{NN}} =200$ GeV and by ALICE at $\sqrt{s_{NN}} =2.76$ TeV. The most striking result discussed here is that for the most probable chemical freeze-out scenario for the STAR energy the found parameters allow us to reproduce the values of the experimental ratios $S_3$ and $\overline{S}_3$ without fitting.
