  • Coleppa, Baradhwaj; Sarkar, Agnivo; Rai, Santosh Kumar (American Physical Society, 2020-03)
    We study the discovery prospects of the charged Higgs boson in the context of multi-Higgs models in certain beyond the Standard Model scenarios. We classify models into three categories based on the charged Higgs coupling ...
  • Coleppa, Baradhwaj; Kumar, Satendra; Sarkar, Agnivo (American Physical Society (APS), 2018-11)
    Models with extra gauge symmetry are well-motivated extensions of the Standard Model. In this paper, we study an extended gauge model with a heavy neutral gauge boson Z′ which is fermiophobic. Thus, the production of such ...
  • Coleppa, Baradhwaj; Kumar, Mukesh; Kumar, Satendra; Mellado, Bruce (Elsevier, 2017-07)
    We investigate the sensitivity of top-Higgs coupling by considering the associated vertex as CP phase (ζt) dependent through the process View the MathML source in the future Large Hadron electron Collider. In particular ...
  • Coleppa, Baradhwaj; Fuks, Benjamin; Poulose, P.; Sahoo, Shibananda (American Physical Society, 2018-04)
    We investigate the LHC discovery prospects for a heavy Higgs boson decaying into the standard model Higgs boson and additional weak bosons. We consider a generic model-independent new physics configuration where this decay ...
  • Basak, Tanushree; Coleppa, Baradhwaj; Loho, Kousik (Springer Nature, 2021-06)
    We revisit the two real singlet extension of the Standard Model with a Z2�Z'2 symmetry. One of the singlet scalars S2, by virtue of an unbroken Z'2 symmetry, plays the role of a stable dark matter candidate. The other ...
