  We examine the prospect of observing genuine lepton number violating (LNV)
signals at hadron colliders in the context of the Type II seesaw mechanism. The
model features smoking gun signals involving same-sign di-leptons and jets that
may be the primary observable channel in certain regions of the parameter
space. The flavour composition of final-state charged leptons in the minimal
model is related to the origin of neutrino masses and is correlated with other
rare processes, such as neutrinoless double beta decay. We review existing
collider limits and provide sensitivity estimates from LNV signals at upcoming
runs of the LHC, for zero and non-zero mass splittings between the scalar
triplet components.
