Search for baryon and lepton number violation decay $D^{\pm}\to n(\bar{n})e^{\pm}$
BESIII Collaboration, М. Н. Ачасов, P. Adlarson, M. Albrecht et autres
Using a data set of electron-positron collisions corresponding to an integrated luminosity of ${\rm 2.93~fb^{-1}}$ taken with the BESIII detector at a center-of-mass energy of 3.773 GeV, a search for the baryon ($B$) and lepton ($L$) number violating decays $D^{\pm}\to n(\bar{n})e^{\pm}$ is …
