Probing TeV-Scale Inverse-Seesaw Leptogenesis and Majorana Dark Matter in Models at Multi-TeV Muon Colliders
Xin-Qiang Li, Himadri Roy, Tripurari Srivastava +2
We investigate a predictive and testable framework in which dark matter (DM), heavy-neutrino dynamics, and the BAU originate from correlated interactions within a local $U(1)_{B-L}…
Fermi-ball in a multicomponent dark matter framework and its gravitational wave signatures
Nabarun Chakrabarty, Indrani Chakraborty, Himadri Roy
It has been known that under-abundant dark matter density of an inert doublet can be replenished by an additional dark matter component, say, a fermion. We find that such a scenari…
Single-step first order phase transition and gravitational waves in a SIMP dark matter scenario
Nabarun Chakrabarty, Himadri Roy, Tripurari Srivastava
We investigate the non-zero temperature dynamics of a sub-GeV dark matter scenario freezing-out via self-interactions. As a prototype, we take up the case of a scalar dark matter s…
Searches for heavy neutrinos at multi-TeV muon collider : a resonant leptogenesis perspective
Indrani Chakraborty, Himadri Roy, Tripurari Srivastava
In this work, the standard model (SM) is extended with two right-handed (RH) neutrinos and two singlet neutral fermions to yield active neutrino masses via (2,2) inverse see-saw me…
Resonant leptogenesis in (2,2) inverse see-saw realisation
Indrani Chakraborty, Himadri Roy, Tripurari Srivastava
In this present work, we uphold the standard model (SM) augmented with two right-handed (RH) neutrinos along with two singlet neutral fermions to generate active neutrino masses vi…
Type-I thermal leptogenesis in -symmetric three Higgs doublet model
Indrani Chakraborty, Himadri Roy
Our present work explores the possibility of neutrino mass generation through {\em Type-I see-saw} mechanism and provides an explanation of the baryon asymmetry of the Universe via…
Prospects for Dark Boson at the LHC
Himadri Roy
Non-Abelian Vector Boson Dark Matter (VBDM), arising from an extension of the Standard Model (SM) has been studied. The Dark Matter (DM) is stabilized by imposing an addi…
Probing individual sources during reionization and cosmic dawn using SKA HI 21-cm observations
Kanan K. Datta, Raghunath Ghara, Suman Majumdar +4
Detection of individual luminous sources during the reionization epoch and cosmic dawn through their signatures in the HI 21-cm signal is one of the direct approaches to probe the…
