Description
The world’s largest samples of $J/\psi$ and $\psi(3686)$ events produced in $e^+e^-$ annihilation provide a clean source of baryon excitations, allowing for a rich baryon spectroscopy programme at BESIII. Based on the large data samples collected by BESIII experiment, the baryon spectroscopy has been studied through decays J/psi -> omega p anti-p, psi(3686) -> Lambda anti-Lambda eta, psi(3686) -> Lambda anti-Lambda omega, e+e- -> Lambda anti-Lambda eta from 3.5106 to 4.6988 GeV and e+e- -> p K- anti-Lambda + c.c. at 4.178 GeV. The recent results for the baryon excited states and threshold enhancement of baryon pairs will be reported in this talk.
