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

BESIII Collaboration, M. Ablikim, M. N. Achasov +655

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 fo…
