Description

In this work, the Standard Model (SM) is
extended with two right-handed (RH) neutrinos and two
singlet neutral fermions to yield active neutrino masses via
(2,2) inverse see-saw mechanism. We first validate the multi-
dimensional model parameter space with neutrino oscillation
data, obeying the experimental bounds coming from the lep-
ton flavor violating (LFV) decays: μ → eγ, τ → eγ, τ →
μγ. Besides we also search for the portion of the parame-
ter space which yield the observed baryon asymmetry of the
universe via resonant leptogenesis. Further, we pick up a few
benchmark points from the aforementioned parameter space
with TeV scale heavy neutrinos and perform an exhaustive
collider analysis of the final states: 2l +ET / and 1 l +2 j + ̸ ET
in multi-TeV muon collider.

New Physics opportunities with low and high energy muon beams none
