Lepton number violating right-sneutrino decays

Presented by Dr. Harri WALTARI on 1 Jul 2019 from 17:00 to 17:20
Type: oral presentation
Track: Collider Probes of New Physics


Lepton number violation is notoriously difficult to observe with left-handed sneutrinos as sneutrino-antisneutrino oscillation requires the sneutrinos to be nearly degenerate. This situation is alleviated with right-handed sneutrinos. We discuss the possibility of observing lepton number violating sneutrino decays in the NMSSM extended with right-handed neutrinos. If higgsinos are lighter than sneutrinos, the sneutrinos may decay visibly and we may obtain a same-sign dilepton signature from sneutrino pair production.
