Gauge Singlet Vector-like Fermion Dark Matter, LHC Diphoton Rate and Direct Detection
Shrihari Gopalakrishna, Tuhin Subhra Mukherjee
We study a gauge-singlet vector-like fermion hidden-sector dark matter model, in which the communication between the dark matter and the visible standard model sector is via the Hi…
The 750 GeV diphoton excess in a two Higgs doublet model and a singlet scalar model, with vector-like fermions, unitarity constraints, and dark matter implications
Shrihari Gopalakrishna, Tuhin Subhra Mukherjee
We explore the possibility of a beyond the standard model scalar () as a possible explanation of the diphoton resonance at 750~GeV invariant mass reported by the ATLAS and CMS c…
Status and Prospects of the Two-Higgs-Doublet SU(6)/Sp(6) little-Higgs Model and the Alignment Limit
Shrihari Gopalakrishna, Tuhin Subhra Mukherjee, Soumya Sadhukhan
We study in detail the little-Higgs model proposed by Low, Skiba and Smith with an SU(6)/Sp(6) group structure. The effective theory at the TeV scale is a two-Higgs doublet model (…
Extra Neutral Scalars with Vector-like Fermions at the LHC
Shrihari Gopalakrishna, Tuhin Subhra Mukherjee, Soumya Sadhukhan
Many theories beyond the standard model (BSM) contain new CP-odd and CP-even neutral scalars , and new vector-like fermions (). The couplings of the CP-odd scal…
