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 / ψ

and 3 billion

ψ (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

C P

violation, rare hyperon decays, hyperon pair production, and hyperon–nucleon interactions.

Keywords: CP violation; electromagnetic form factors; charmonium(-like) states; hyperon–nucleon scattering
