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

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

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