Electromagnetic form factors are fundamental observables that describe the electric and magnetic structure of hadrons. At BESIII, form factors have been measured for different baryons in the time-like region for the first time or with the best precision. The results are presented with examples focusing on, but not limited to, the proton/neutron, the Lambda with a strange quark, and the Lambda(c) with a charm quark.
Electromagnetic form factors are fundamental observables that describe the electric and magnetic structure of hadrons and provide keys to understand the strong interaction. At the Beijing Spectrometer (BESIII), form factors have been measured for different baryons in the time-like region for the first time or with the best precision. The results are presented with examples focused on but not limited to the proton/neutron, the Lambda, with a strange quark, and the Lambda(c), with a charm quark.
