论文摘要
最近开发的具有多组分硬核排斥力的强子共振气体模型用于解决和解决长期存在的问题，以描述由恒星协作测量的轻核簇倍增性，包括STAR协作（称为Hyper-Triton Chemell-Triton Chemical Freeze-out up upeal）。对于在碰撞能量$ \ sqrt {s_ {nn}} = 200 $ GEV和爱丽丝AT $ \ sqrt {s_ {nn}} = 2.76 $ tev时，获得了由星在碰撞能量$ \ sqrt {s_ {nn}} = 200 $ GEV处测量的HADRONIC和其他光核聚类数据的准确描述。通过应用分析光核簇数据的新策略以及使用（反 - ）$λ$ hyperos的硬核半径的值来实现这一成功。当前工作中最引人注目的结果之一是，对于最可能的化学冻结场景，获得的参数允许同时重现实验比的值$ s_3 $和$ \ bar {s} _3 $，而该值未包含在适合中。
The recently developed hadron resonance gas model with multicomponent hard-core repulsion is used to address and resolve the long standing problem to describe the light nuclear cluster multiplicities including the hyper-triton measured by the STAR Collaboration, known as the hyper-triton chemical freeze-out puzzle. An unprecedentedly accurate description is obtained for the hadronic and other light nuclear cluster data measured by STAR at the collision energy $\sqrt{s_{NN}} =200$ GeV and by ALICE at $\sqrt{s_{NN}} =2.76$ TeV. This success is achieved by applying the new strategy of analyzing the light nuclear cluster data and by using the value for the hard-core radius of the (anti-)$Λ$ hyperons found in earlier work. One of the most striking results of the present work is that for the most probable scenario of chemical freeze-out for the STAR energy the obtained parameters allow to simultaneously reproduce the values of the experimental ratios $S_3$ and $\bar{S}_3$ which were not included in the fit.
