Search for the baryon and lepton number violating decay $J/\psi \to p{e}^{-}$ + c.c

BESIII Collaboration, M. Ablikim, M. N. Achasov +667

Based on $(2712.4\pm 14.3)\times 10^6$ $\psi (3686)$ events collected by the BESIII detector operating at the BEPCII storage ring, we perform a search for the baryon- and lepton-…
