Description
The type II seesaw mechanism introduces a triplet boson to explain the observed neutrino masses and mixing. As a result, the model predicts a peculiar signature of a doubly charged boson decaying into di-leptons which is being probed at the LHC. In this talk, I will discuss LHC phenomenology of type II seesaw focusing on novel same-sign tetra-lepton signals which originates from triplet-antitriplet oscillation allowed in some specific parameter space of the model.
