A Review of Hyperon Physics at BESIII Experiment

Abstract

The BESIII Collaboration has collected large data samples from $e^{+}{e}^{-}$ collisions at center-of-mass energies ranging from 1.84 to 4.95 GeV, which include the world's largest charmonium sample, consisting of 10 billion $J/\psi$ and 3 billion $\psi (3686)$ events. These high-statistics datasets enable BESIII to carry out a wide range of studies in hyperon physics. In this article, we review the major achievements of the BESIII Collaboration in this field, which can be broadly categorized into four areas: hyperon polarization and $CP$ violation, rare hyperon decays, hyperon pair production, and hyperon-nucleon interactions.
