Measurements of Sigma+ and Sigma- Time-like Electromagnetic Form Factors for center-of-mass energies from 2.3864 to 3.0200 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +494

The Born cross sections of the $e^{+}{e}^{-}\to {\Sigma }^{+}{\bar{\Sigma }}^{-}$ and $e^{+}{e}^{-}\to {\Sigma }^{-}{\bar{\Sigma }}^{+}$ processes are determined with high precision for center-of-mass energy from 2.3864 to…
