标题： Extracting baryon-antibaryon strong interaction potentials from p$\barΛ$ femtoscopic correlation function

摘要： STAR实验测量了在$\sqrt{s_{NN}}=200$ GeV 的中心Au+Au碰撞中$p\Lambda$、$\bar{p}\bar{\Lambda}$、$\bar{p}\Lambda$和$p\bar{\Lambda}$的费米尺度相关函数。 提取的$p\Lambda$和$\bar{p}\bar{\Lambda}$的系统尺寸与模型预期和其他对类型的结果一致，而$p\bar{\Lambda}$和$\bar{p}\Lambda$的结果则不一致且明显较低。 此外，尝试提取该重子-反重子（$B\bar{B}$）对的强相互作用势的未知参数。 在本工作中，我们重新分析了STAR数据，考虑了来自更重的$B\bar{B}$对的剩余费米尺度相关性。 我们得到了系统大小的新估计，这与$p\Lambda$和$\bar{p}\bar{\Lambda}$对的结果一致，并符合模型预期。 我们给出了$p\bar{\Lambda}$的强相互作用势参数的新估计，并表明可以对其他更重的$B\bar{B}$对的参数施加类似的约束。 显示英文摘要

摘要： The STAR experiment has measured $p\Lambda$, $\bar{p}\bar{\Lambda}$, $\bar{p}\Lambda$, and $p\bar{\Lambda}$ femtoscopic correlation functions in central Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV. The system size extracted for $p\Lambda$ and $\bar{p}\bar{\Lambda}$ is consistent with model expectations and results for other pair types, while for $p\bar{\Lambda}$ and $\bar{p}\Lambda$ it is not consistent with the other two and significantly lower. In addition an attempt was made to extract the unknown parameters of the strong interaction potential for this baryon-antibaryon ($B\bar{B}$) pair. In this work we reanalyze the STAR data, taking into account residual femtoscopic correlations from heavier $B\bar{B}$ pairs. We obtain new estimates for the system size, consistent with the results for $p\Lambda$ and $\bar{p}\bar{\Lambda}$ pairs and with model expectations. We give new estimates for the strong interaction potential parameters for $p\bar{\Lambda}$ and show that similar constraints can be given for parameters for other, heavier $B\bar{B}$ pairs.
