Probing Fermion-Portal Scalar Dark Matter through Charged Vector-Like Fermions at Future Muon Colliders

Songshaptak De, Tapoja Jha, Najimuddin Khan +1

We revisit a minimal fermion-portal scalar dark matter model consisting of a real singlet scalar dark matter candidate and additional vector-like singlet and doublet charged fermio…

Finding flavons at colliders

Gauhar Abbas, Ashutosh Kumar Alok, Neetu Raj Singh Chundawat +2

We conduct a comprehensive investigation into the flavour phenomenology and collider signatures of flavon of flavour symmetries for…

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…

A 17 MeV pseudoscalar and the LSND, MiniBooNE and ATOMKI anomalies

Waleed Abdallah, Raj Gandhi, Tathagata Ghosh +3

In the absence of any new physics signals at the Large Hadron Collider (LHC), anomalous results at low energy experiments have become the subject of increased attention. We focus o…

Exploring the Dark Sector of the inspired FNSM at the LHC

Amit Chakraborty, Dilip Kumar Ghosh, Najimuddin Khan +1

We establish the possibility of having a pseudo-Nambu-Goldstone boson (pNGB) Dark Matter (DM) candidate in the inspired Froggatt-Nielsen Singlet Model (iFNSM) wherein a direct conn…

Origin of neutrino masses, dark matter, leptogenesis, and inflation in a seesaw model with triplets

Pritam Das, Najimuddin Khan

We consider a new physics model, where the Standard Model (SM) is extended by hyperchargeless triplet fermions and Higgs triplet with hypercharge . The first two generat…
