Our objective is to focus on extensions of the Standard Model and build such models that can be probed in current or near future experiments. Various Colliders, i.e. ATLAS, CMS, LHCb, Belle-II, etc., Beam Dump, i.e. NA64(e++ ), AWAKE, HPS, Sea Quest at Fermilab, and Direct-Detection, i.e. XENONnT, LZ, XMASS-II, and SENSEI, experiments yield strong limitations on such models, allowing us to confine the parameters of such theories and witness the impact of novel physics.

We worked on various aspects of model building, starting fundamentally from gauge anomaly cancellations and new gauge symmetries. Recently we studied the self-energy corrections to the gauge bosons and the parametrization of dominant BSM effects in terms of oblique parameters (S, T, U). These parameters encompass the effects of new physics provided the new physics mass scale is bigger than the electroweak scale. We applied this method to calculate loop corrections to W mass. We explored the possibility of the Canonical Scotogenic model to explain the W boson anomaly. In another work, we focused on the chiral solution of the gauged "B-L " model and attempted to investigate it in relation to the W anomaly. We also studied Constraints on Dark matter from relic density and direct detection experiments in these models.

We are also interested in various neutrino properties, i.e. Neutrino-Oscillations, Lepton flavour violation, Neutrino mass mechanism, and in low-energy processes, i.e. Coherent elastic neutrino-nucleus scattering, elastic neutrino electron scattering, and Dark matter electron/nucleus scattering [doi.org/10.1016/j.physletb.2023.137742] [arXiv:2208.06415 [hep-ph]].

With four parameters I can fit an elephant, and with five I can make him wiggle his trunk.

In the absence of experimental evidence, basic beliefs of theoretical physicists may initially have almost a religious flavor, guided by faith and aesthetics. Fortunately, unlike religion, these beliefs soon face the hard test of experiment.
