标题： Hyperon Pair Production at BESIII

摘要： 这份海报展示了来自BESIII实验的最新实验结果，包括两类研究。 首先，它报告了在过程$e^+e^- \to \Lambda\bar\Lambda$，$\Sigma^+\bar\Sigma^-$，$\Sigma^0\bar\Sigma^0$，$\Xi^0\bar\Xi^0$和$\Xi^-\bar\Xi^+$中的超子对产生研究。 这些过程的玻恩截面在质心系能量从$3.5$到$4.9$GeV 的范围内被测量。 首次发现了 $\psi(3770)\to\Lambda\bar\Lambda$ 和 $\Xi^-\bar\Xi^+$ 的衰变证据。 其次，它报告了涉及超子末态的多体衰变的布恩截面测量结果。 发现了 $\psi(4160)\to K^-\bar\Xi^+\Lambda+c.c.$ 的证据。 这些结果为超子在 $e^+e^-$ 粒子湮灭中的产生以及矢量魅夸克态（类似）的衰变机制提供了新的视角，有助于我们对强子动力学的理解。 显示英文摘要

摘要： This poster presents recent experimental findings from the BESIII experiment, including two categories of studies. Firstly, it reports the studies on the hyperon pair production in the processes $e^+e^- \to \Lambda\bar\Lambda$, $\Sigma^+\bar\Sigma^-$, $\Sigma^0\bar\Sigma^0$, $\Xi^0\bar\Xi^0$ and $\Xi^-\bar\Xi^+$. The Born cross sections for these processes are measured at center-of-mass energies ranging from $3.5$ to $4.9$ GeV. For the first time, evidence for the decays $\psi(3770)\to\Lambda\bar\Lambda$ and $\Xi^-\bar\Xi^+$ is found. Secondly, it reports the measurements of the Born cross sections of multi-body decays involving hyperon final states. The evidence of $\psi(4160)\to K^-\bar\Xi^+\Lambda+c.c.$ is found. These results offer new perspectives on hyperon production in $e^+e^-$ annihilation and the decay mechanism of vector charmonium(-like) states, contributing to our understanding of hadron dynamics.
