Determination of the ${\Sigma }^{+}$ Timelike Electromagnetic Form Factors

BESIII Collaboration, M. Ablikim, M. N. Achasov +615

Based on data samples collected with the BESIII detector at the BEPCII collider, the process $e^{+}{e}^{-}\to {\Sigma }^{+}{\bar{\Sigma }}^{-}$ is studied at center-of-mass energies $\sqrt{s}$ = 2.39…
