Measurement of Baryon Electromagnetic Form Factors at BESIII

Abstract

The Beijing $e^{+}{e}^{-}$-collider (BEPCII) is a double-ring symmetric collider running at center-of-mass energies between 2.0 and 4.6 GeV. This energy range allows the BESIII-experiment to measure baryon electromagnetic form factors in direct $e^{+}{e}^{-}$-annihilation and in initial state radiation processes. In this paper, results on $e^{+}{e}^{-}\to p\bar{p}$ and $e^{+}{e}^{-}\to \Lambda \bar{\Lambda }$ based on data collected by BESIII in 2011 and 2012 are presented. Expectations from the BESIII high luminosity energy scan from 2015 and from radiative return at different center-of-mass energies are also reported.
