Evidence for the semileptonic decays ${\Lambda }_c^{+}\to {\Sigma }^{\pm }{\pi }^{\mp }{e}^{+}{\nu }_e$

BESIII Collaboration, M. Ablikim, M. N. Achasov +680

Using $4.5f{b}^{-1}$ of $e^{+}{e}^{-}$ collision data collected by the BESIII detector at center-of-mass energies between $4.600$ and $4.699GeV$, we search for the semileptonic decays…
