Signals for a 2HDM with at the LHC
Anjan Kumar Barik, Santosh Kumar Rai, Agnivo Sarkar
We consider a neutrinophilic extension of the Standard Model (SM) under which only a second Higgs doublet and SM singlet scalars and fermions are charged. The new gauge boso…
Discovering an invisible Z' at the muon collider
Anjan Kumar Barik, Santosh Kumar Rai, Aviral Srivastava
We show in this letter how a heavy invisible gauge boson that will practically be out of reach of the Large Hadron Collider (LHC), can be discovered at th…
A Scotogenic model with U(1) symmetry and a scalar dark matter
Anjan Kumar Barik, Najimuddin Khan, Santosh Kumar Rai
We study a scotogenic model augmented with an additional U(1) gauge and a discrete Z2 symmetry. The lightest Z2-odd particle in our model becomes the dark matter (DM) candidate whi…
Improving Heavy Dijet Resonance Searches Using Jet Substructure at the LHC
Aruna Kumar Nayak, Santosh Kumar Rai, Tousik Samui
The search for new physics at high energy accelerators has been at the crossroads with very little hint of signals suggesting otherwise. The challenges at a hadronic machine such a…
Heavy Neutrino as Dark Matter in a Neutrinophilic U(1) Model
Waleed Abdallah, Anjan Kumar Barik, Santosh Kumar Rai +1
We study the prospect of heavy singlet neutrinos as a dark matter (DM) candidate within a neutrinophilic U(1) model, where the Standard Model (SM) is extended with a U(1) gauge sym…
Search For a Leptoquark and Vector-like Lepton in a Muon Collider
Nivedita Ghosh, Santosh Kumar Rai, Tousik Samui
The proposal for a high-energy muon collider offers many opportunities in the search for physics beyond the Standard Model (BSM). The collider by construction is likely to be more…
