标题： $^3$H and $^3$He nuclei production in a combined thermal and coalescence framework for heavy-ion collisions in the few-GeV energy regime

摘要： 描述重离子碰撞中GeV能区强子产生的热模型与核子凝聚的思想相结合，用于预测 $^3$H 和 $^3$He 核的产生。 使用了冻结条件的真实参数化，很好地再现了质子和π介子的谱。 它还正确地预测了与实验值相符的氘核产额。 预测的 $^3$H 和 $^3$He 产额似乎比实验结果小约两倍。 模型对谱的预测可以与未来的实验数据进行比较。 显示英文摘要

摘要： A thermal model describing hadron production in heavy-ion collisions in the few-GeV energy regime is combined with the idea of nucleon coalescence to make predictions for the $^3$H and $^3$He nuclei production. A realistic parametrization of the freeze-out conditions is used, which reproduces well the spectra of protons and pions. It also correctly predicts the deuteron yield that agrees with the experimental value. The predicted yields of $^3$H and $^3$He appear to be smaller by about a factor of two compared to the experimental results. The model predictions for the spectra can be compared with future experimental data.
