Hyperon physics at BESIII
\nThe BESIII experiment has been successfully operating at the BEPCII collider since 2008, collecting extensive data samples at the resonances J/ψ and ψ(2S). Recently, BESIII has presented a series of analyses focusing on hyperon physics, particularly the production of hyperon-antihyperon pairs from charmonium states. The polarizations of Ξ− and Ξ0 hyperons have been accurately measured at BESIII, providing a new avenue to test the CP symmetry of multi-strange hyperons. Additionally, BESIII has determined the absolute branching fractions and angular distribution parameters αγ in Λ and Σ+ radiative hyperon decays with significantly higher accuracy than previous measurements. BESIII has also reported on the interactions of Ξ0 and Λ hyperons with nuclei. In this proceeding, we present a comprehensive review of the recent advancements in hyperon physics achieved by the BESIII experiment.\n
