abstract

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 lepton flavor violating (LFV) decays: $\mu \to e \gamma,~ \tau \to e \gamma, ~ \tau \to \mu \gamma$. Besides we also search for the portion of the parameter 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: $2l + \mET$ in multi-TeV muon collider.

    hep-ph 2026-01 conditional novelty 6.0 of 10

    Graviton- and radion-mediated freeze-in in a Randall-Sundrum model can match the observed dark matter relic abundance, and TeV-scale resonant leptogenesis through the same portals can match the observed baryon asymmet...

  2. Vector Portals at Future Lepton Colliders

    hep-ph 2024-12 conditional novelty 6.0 of 10

    Future lepton colliders could probe dark photon and L_mu-L_tau vector portals with one to two orders of magnitude better sensitivity than current constraints across masses from tens of GeV to a few TeV.

  3. High-energy cLFV at $\mu$TRISTAN: HNL extensions of the Standard Model

    hep-ph 2024-12 conditional novelty 6.0 of 10

    In HNL extensions of the Standard Model, mu+e- collisions at muTRISTAN could discover e-tau and mu-tau charged lepton flavour violation with sensitivity orders of magnitude beyond low-energy experiments and FCC-ee.
