Description

Hyperons offer a distinctive approach for studying the strong interaction, and their production in $e^+e^-$ collisions constitutes a novel and feasible means to acquire information for comprehending hyperon structure, internal dynamics, and even the nature of charmonium(-like) states. With the unique datasets obtained by the BESIII experiment, the recent findings regarding the hyperon pair production in $e^+e^-$ collisions are presented, such as $e^+e^-\to\Lambda\bar\Lambda$, $\Sigma^0\bar\Sigma^0$, $\Sigma^+\bar\Sigma^-$, $\Xi^0\bar\Xi^0$, and $\Xi^-\bar\Xi^+$, and so forth. These results provide new viewpoints on hadron production in the hyperson final states, contributing to our understanding of hadron dynamics in this energy regime.
