Abstract

Hyperons provide a unique avenue to study the strong interaction. Due to their limited lifetime, the hyperon production in e +e − collisions is a new viable way to obtain information to understand the hyperon structure and internal dynamics, and even insight into the nature of the charmonium(-like) states. With the unique data sets obtained by the BESIII experiment, the recent results for the hyperon pair production in e +e − collisions are presented, such as observation of ψ(3686) → Ξ(1530)−Ξ(1530) ¯ +, determination of the Ω − spin, observation of the Ξ hyperon polarization, study of threshold effect in the sector of Ξ hyperon, search for Y (4230/4260) → Ξ −Ξ¯+ and so on.
