Generation of Neutrino mass from new physics at TeV scale and Multi-lepton Signatures at the LHC

Understand

In this paper we consider generation of naturally small neutrino masses from a dimension-7 operator.

• Such a term can arise in presence of a scalar quadruplet and a pair of vector-like fermion triplets and enables one to obtain small neutrino masses through TeV scale linear seesaw mechanism.
• We study the phenomenology of the charged scalars of this model, in particular, the multi-lepton signatures at the Large Hadron Collider.
• Of special importance are the presence of the same-sign-tri-lepton signatures originating from the triply-charged scalars.
