Lepton Collider as a Window to Reheating via Freezing Out Dark Matter Detection
Subhaditya Bhattacharya, Anupam Ghosh, Niloy Mondal +1
We investigate a particle dark matter (DM) scenario where the DM interaction with the Standard Model are mediated by a leptophilic effective operator. Unlike conventional WIMP scen…
Illuminating Degenerate Dark Sector of Inert Doublet Model at Muon Collider
Anupam Ghosh, Partha Konar, Chandrima Sen +1
The Inert scalar Doublet Model (IDM) presents a simple yet elegant framework for a scalar dark sector where the lightest mode functions as a viable dark matter candidate under a $\…
Jet Substructure Probe on Scalar Leptoquark Models via Top Polarization
Anupam Ghosh, Partha Konar, Tousik Samui +1
The study of leptoquarks and their couplings to fermions with different chiralities provides a powerful tool for distinguishing among different leptoquark models. As a case study,…
Collider fingerprints of freeze-in dark matter produced during the fast expansion phase of Universe
Anupam Ghosh, Partha Konar, Sudipta Show
We examine a simple dark sector extension where the observed dark matter (DM) abundance arises from a freeze-in process through the decay of heavy vector-like quarks into a scalar…
