Searching for charged Higgs bosons in top decays via the channel
Saiyad Ashanujjaman, Guglielmo Coloretti, Andreas Crivellin +2
Rare top-quark decays offer a sensitive probe of charged Higgs bosons with masses below the top mass, owing to the large production rate at the LHC and the distinctive fi…
Indications for New Higgs Bosons
Andreas Crivellin, Saiyad Ashanujjaman, Sumit Banik +2
After the Higgs discovery, the question of whether particles beyond those of the Standard Model exist is more pressing than ever. In this context, the scalar sector is particularly…
Searching for a Charged Higgs Boson in Top-Quark Decays via the Mode
Saiyad Ashanujjaman, Andreas Crivellin, Siddharth P. Maharathy +1
Top-quark decays are sensitive probes of light charged Higgs bosons () due to the sizable production cross section at the LHC in conjunction with their distinct ex…
Vacuum structure of the Babu-Nandi-Tavartkiladze model of neutrino mass generation
Saiyad Ashanujjaman, Siddharth P. Maharathy
We analyze the vacuum structure of the Babu--Nandi--Tavartkiladze (BNT) model of neutrino mass generation, in which the Standard Model is extended by an scalar quadruplet…
Precision Higgs Boson Probe of Type-II Seesaw Models
Saiyad Ashanujjaman, P. S. Bhupal Dev, Jihong Huang +1
Despite direct searches at the LHC excluding tripletlike Higgs bosons up to several hundred GeV over much of the type-II seesaw model parameter space, parts of it -- most notably t…
Constraining with in the Low-Mass Region
Saiyad Ashanujjaman, Guglielmo Coloretti, Andreas Crivellin +2
The decay is a characteristic signal of two-Higgs-doublet models (2HDMs), where and lie primarily within the same multiplet, leading to a coupling of or…
