Recent results of Baryon electromagnetic form factors at BESIII

Abstract

Baryon Electromagnetic Form Factors are essential for testing ground state models of nucleon internal structures. At the BESIII experiment, a comprehensive study has been conducted on the electromagnetic form factors of various baryons. The electromagnetic form factor ratio of the nucleon (proton and neutron), denoted as |GE/GM|, has been determined with high precision. And the study at BESIII has explored the cross sections of various baryon pairs, including Λ, Λc, Σ, Ξ, Ω and Δ from their respective thresholds. In the study conducted at BESIII, threshold effects have been observed in some baryon pairs, enhancing our understanding of these baryon interactions.
