Measurement of Branching Fraction and Transition Magnetic Moment of the Hyperon Dalitz Decay ${\Sigma }^0\to \Lambda e^{+}{e}^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +685

Based on a data sample of 10 billion $J/\psi$ events collected with the BESIII detector operating at the BEPCII collider, the Dalitz decay ${\Sigma }^0\to \Lambda e^{+}{e}^{-}$ is studied experim…
