Abstract In the Dynamical Scotogenic Model, the global B − L symmetry is supposed to be broken spontaneously resulting in a massless Goldstone boson called majoron, and massive right handed neutrinos which participate in the generation of light neu

Abstract We study a different variant of left-right symmetric model, incorporating Dirac type neutrinos. In the absence of the bi-doublet scalars, the possibility of a universal seesaw type of mass generation mechanism for all the Standard Model char

Doubly-charged Higgs bosons have extensively been searched at the LHC. In this work, we study the sensitivity reach of the doubly-charged scalar (H±±) in muon collider for the well-known Type-II seesaw scenario. First, we perform a cut-based analys

Abstract We present an extension of the SM involving three triplet fermions, one triplet scalar and one singlet fermion, which can explain both neutrino masses and dark matter. One triplet of fermions and the singlet are odd under a Z 2 symmetry, thu

Abstract We investigate the pair-production of Right-Handed Neutrinos (RHNs) via a $$B-L$$ B - L $$Z'$$ Z ′ boson and present the sensitivity studies of the active-sterile neutrino mixing ( $$|V_{\mu N}|$$ | V μ N | ) at the High-Luminosity run of

Abstract In a simple extension of the standard model (SM), a pair of vector like lepton doublets (L 1 and L 2) and a SU(2) L scalar doublet (η) have been introduced to help in accommodating the discrepancy in determination of the anomalous magnetic

Abstract Extending the Standard Model with right-handed neutrinos (RHNs) is well motivated by the observation of neutrino oscillations. In the type-I seesaw model, the RHNs interact with the SM particles via tiny mixings with the active neutrinos, wh

Abstract We consider the gauged B − L model which is extended with a secluded dark sector, comprising of two dark sector particles. In this framework the lightest Z $$ \mathcal{Z} $$ 2-odd particle is the dark matter candidate, having a feeble inte

Abstract The various global analyses of available neutrino oscillation data indicate the presence of the standard 3 + 0 neutrino oscillation picture. However, there are a few short baseline anomalies that point to the possible existence of a fourth n

Abstract We explore relativistic freeze-in production of scalar dark matter in gauged B − L model, where we focus on the production of dark matter from the decay and annihilation of Standard Model (SM) and B − L Higgs bosons. We consider the Bose
