Search for lepton number violating decays of $D_s^+\to h^-h^0e^+e^+$

BESIII Collaboration, M. Ablikim, М. Н. Ачасов, P. Adlarson et autres

Based on 7.33 fb$^{-1}$ of $e^+e^-$ collision data collected by the BESIII detector operating at the BEPCII collider at center-of-mass energies from 4.128 to 4.226 GeV, a search for the Majorana neutrino $ν_m$ is conducted in the lepton-number-violating decays of $D_s^+\to h^-h^0e^+e^+$. …

Search for the lepton number violating decay Σ − → p e − e − and the rare inclusive decay Σ − → Σ + X

Using a data sample of $(1310.6\ifmmode\pm\else\textpm\fi{}7.0)\ifmmode\times\else\texttimes\fi{}{10}^{6}\text{ }\text{ }J/\ensuremath{\psi}$ events taken with the BESIII detector at the center-of-mass energy of 3.097 GeV, we search for the first time for the lepton number violating decay ${\mathrm{\ensuremath{\Sigma}}}^{\ensuremath{-}}\ensuremath{\rightarrow}p{e}^{\ensuremath{-}}{e}^{\ensuremath{-}}$ and the rare inclusive decay ${\mathrm{\ensuremath{\Sigma}}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Sigma}}}^{+}X$, where $X$ …
