Vanilla Scotogenic Model at the future Muon Collider

Niloy Mondal, Dipankar Pradhan, Abhik Sarkar +2

The vanilla scotogenic model (VSM) featuring three right-handed neutrinos and an inert scalar doublet, offers a unified explanation of neutrino masses, dark matter (DM), and the ba…

Complex Scalar Dark Matter with a Vector-Like Quark and Lepton: Precision, Flavor, and HL-LHC

Lipika Kolay, Rusa Mandal, Manimala Mitra +2

We investigate a minimal extension of the SM consisting of a -stabilized complex scalar dark matter (CSDM) candidate, a down-type vector-like quark (VLQ), and a charg…

From WIMP to FIMP during reheating: collider vs non-collider probes for p-wave annihilation

Dipankar Pradhan, Niloy Mondal, Abhik Sarkar +4

By examining the transition from freeze-out to freeze-in dark matter (DM) production within the framework of perturbative reheating, where DM interacts with the visible sector thro…

Multi-messenger FIMP

Debasish Borah, Nayan Das, Sahabub Jahedi +1

We propose a multi-messenger frontier probe of non-thermal or freeze-in massive particle (FIMP) dark matter (DM) by considering an effective field theory (EFT) setup. Assuming lept…

Up-type FCNC in presence of Dark Matter

Subhaditya Bhattacharya, Lipika Kolay, Dipankar Pradhan +1

Dark Matter (DM) is a known unknown. Apart, current experimental constraints on flavor-changing neutral current (FCNC) processes involving up-type quarks also provide scope to expl…

Direct Search signal of two-component Dark Matter

Subhaditya Bhattacharya, Dipankar Pradhan

How do we know if the dark sector consists of more than one dark matter (DM) component is an important question, for which the answer is not very definite. In this article we study…

Two-component Dark Matter and low scale Thermal Leptogenesis

Subhaditya Bhattacharya, Devabrat Mahanta, Niloy Mondal +1

The observable cosmos exhibits sizable baryon asymmetry, small active neutrino masses, and the presence of dark matter (DM). To address these phenomena together, we propose a two c…

Pseudo-FIMP dark matter in presence of a SIMP

Subhaditya Bhattacharya, Dipankar Pradhan, Jahaan Thakkar

Pseudo-feebly Interacting Massive Particle (pFIMP) has been postulated in two component dark matter (DM) scenarios, where it has feeble interaction with the visible sector, but siz…

The Influence of Lepton Portal on the WIMP-pFIMP framework

Jayita Lahiri, Dipankar Pradhan, Abhik Sarkar

The dynamics and detection possibility of a pseudo-FIMP (pFIMP) dark matter (DM) in the presence of a thermal DM have been studied in different contexts. The pFIMP phenomenology la…

Lepton collider as a window to reheating via freezing in dark matter detection. Part II

Basabendu Barman, Subhaditya Bhattacharya, Sahabub Jahedi +2

Dark matter (DM) genesis via Ultraviolet (UV) freeze-in embeds the seed of reheating temperature and dynamics in its relic density. Thus, discovery of such a DM candidate can possi…

Multiparticle scalar dark matter with symmetry

Subhaditya Bhattacharya, Lipika Kolay, Dipankar Pradhan

More than one dark sector particle transforming under the same symmetry provides one stable dark matter (DM) component which undergoes co-annihilation with the heavier particle(s)…

Lepton collider as a window to reheating via freezing in dark matter detection. Part I

Basabendu Barman, Subhaditya Bhattacharya, Sahabub Jahedi +2

We propose a methodology to infer the reheat temperature () of the Universe from the collider signal of freezing in dark matter (DM). We demonstrate it for the mono-…

Detection possibility of a Pseudo-FIMP in presence of a thermal WIMP

Subhaditya Bhattacharya, Jayita Lahiri, Dipankar Pradhan

A dark matter (DM) having feeble interaction with the visible sector can thermalise via substantial interaction with a Weakly Interacting Massive Particle (WIMP). Such DM candidate…

Dynamics of the pseudo-FIMP in presence of a thermal Dark Matter

Subhaditya Bhattacharya, Jayita Lahiri, Dipankar Pradhan

We demonstrate that in a two component dark matter (DM) set up, when DM is equilibrated with the thermal bath, the other DM, in spite of having feeble or negligible interac…

Electroweak Symmetry Breaking and WIMP-FIMP Dark Matter

Subhaditya Bhattacharya, Sreemanti Chakraborti, Dipankar Pradhan

Electroweak Symmetry Breaking (EWSB) is known to produce a massive universe that we live in. However, it may also provide an important boundary for freeze-in or freeze-out of dark…
