BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres
The Cabibbo-allowed weak radiative decay $Λ_{c}^+\to Σ^+γ$ has been searched for in a sample of $Λ_{c}^+\barΛ_{c}^-$ pairs produced in $e^+e^-$ annihilations, corresponding to an integrated luminosity of $4.5 \mathrm{fb}^{-1}$ collected with the BESIII detector at center-of-mass energies between 4.60 and 4.70 GeV. …
