1. Scrutinizing right-handed neutrino portal dark matter with Yukawa effect / Bandyopadhyay, Priyotosh ; Chun, Eung Jin ; Mandal, Rusa ; Queiroz, Farinaldo S.
Analyzing the neutrino Yukawa effect in the freeze-out process of a generic dark matter candidate with right-handed neutrino portal, we identify the parameter regions satisfying the observed dark matter relic density as well as the current Fermi-LAT and H.E.S.S. [...]

3. Scalar dark matter in leptophilic two-Higgs-doublet model / Bandyopadhyay, Priyotosh ; Chun, Eung Jin ; Mandal, Rusa
Two-Higgs-Doublet Model of Type-X in the large tan⁡β limit becomes leptophilic to allow a light pseudo-scalar A and thus provides an explanation of the muon g−2 anomaly. [...]

4. Distinguishing charged Higgs bosons from different representations at the LHC / Bandyopadhyay, Priyotosh ; Costantini, Antonio
Extending the Standard Model (SM) scalar sector via the addition of one or more Higgs fields in higher dimensional representations adds one or more charged Higgs bosons to the spectrum. [...]
