Study of baryon pair production at BESIII

The BESIII detector at BEPCII Collider has collected the world’s largest data sets. Some of recent results on the baryon pair production in charmonium(-like) decays, 𝐽 / 𝜓 , 𝜓 ( 3686 ) , etc., and in the positron-electron annihilation are reported, which covers the observation of more charmonium modes, the measurement of triply-strange baryon polarization, most accurate measurements of nucleon form factor, and more precise studies for baryon pair production near threshold. These results provide a rich laboratory to test the standard model, such as probing the limitation of the quark models and spotting unrevealed aspects of the QCD description of the structure of hadron resonances.
