论文摘要
已经研究了化学冷冻处的光核的热描述。首先，我已经验证了光核的平衡，然后引入了一种研究光核形成的新方法。一个人可以研究光核比率的相空间密度与其耐达成分之间的接近度，例如$ \ bar {d}/d $和$（\ bar {p} \ bar {n}/pn）$。我发现，由于在热模型中排除了从辐射率的衰减馈电馈电，因此，辐射表示与光核比率具有良好的一致性。我进行了类似的分析，其比率为$λ$ -Hypernuclei和$^3 he $，这与$λ/p $的比率有关。在这种情况下，也已经研究了陌生人口因子$ s_3 $。这些结果表明，核和高核形成可能发生在标准的化学冷冻液附近和辐射共振之前。该方法将作为讨论光核形成并将衰减纳入其望态成分的指南。
The thermal description of light nuclei at the chemical freeze-out has been investigated. First, I have verified the equilibration of the light nuclei and then introduced a new method to investigate the light nuclei formation. One can study the proximity between the phase space density of light nuclei ratios and their hadronic constituents e.g $\bar{d}/d$ and $(\bar{p}\bar{n}/pn)$. I have found that with the exclusion of the decay feed-down from the hadronic yields in the thermal model, the hadronic representations have good agreement with the light nuclei ratios. I have performed a similar analysis with the ratio of $Λ$-hypernuclei and $^3 He$, which is related to the ratio $Λ/p$. In this context, the strangeness population factor $S_3$ has been studied also. These results indicate that the nuclei and hypernuclei formation may occur near the standard chemical freeze-out and before the decay of the hadronic resonances. This method will serve as a guideline to discuss the light nuclei formation and the inclusion of decay into their hadronic constituents.
