Description
The Beijing Spectrometer (BESIII) at the Beijing Electron Positron Collider in China is an excellent laboratory for the measurement of baryon electromagnetic form factors in the time-like kinematic region.
The collider is running at center-of-mass energies between 2.0 and 4.6 GeV, allowing the study of e+e- annihilations into pairs of baryons like proton-antiproton, neutron-antineutron and hyperons in the SU(3) spin 1/2 octet and spin 3/2 decuplet. Furthermore, the emission of initial-state radiation by the beams allows also to access kinematic regions below the actual center-of-mass energy of the collider, making possible the measurement of baryon form factors also at the production threshold.
In this talk I will review some of the channels currently being studied by the BESIII collaboration.
