On Lepton Number Violation in Type II Seesaw (17'+3')

Speaker

Jonathan Kriewald (IJS)

Description

We determine the prospect of observing genuine lepton number violating (LNV) signals at hadron
colliders in the context of type II seesaw.
The model features smoking gun signals with same-sign di-leptons and jets that may be the
primary observable channel in a certain portion of parameter space.
The charged lepton flavour composition in the minimal model relates to the origin of neutrino mass
and correlates with other rare processes, such as neutrinoless double beta decay.
We review the existing collider limits and provide sensitivity estimates of LNV signals, with
degenerate masses and with mass splittings, for the upcoming runs at the LHC.
