Mono-Z signal for dark matter searches at future lepton colliders and cosmological interpretation
Anupam Ghosh, Partha Kumar Paul, Abhik Sarkar +4
We investigate mono- signature at the future electron-positron collider within the dark matter effective field theory (DMEFT) framework, considering operators up to dimension si…
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…
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 $\…
Electroweak Phase Transition, Gravitational Waves and Collider Probes in Multi-Scalar Dark Matter Scenarios
Tripurari Srivastava, Jaydeb Das, Anupam Ghosh +1
We study scalar singlet extensions of the Standard Model (SM), focusing on scenarios where dark matter (DM) is stabilized by a \(\mathbb{Z}_2\) symmetry. In the minimal single-scal…
Improving sensitivity of vectorlike top partner searches with jet substructure
Anupam Ghosh, Soumyadip Ghosh, Soureek Mitra +2
Vectorlike quark partners appear in many BSM models and remain an important area of research, as they can offer insights into the electroweak symmetry breaking mechanism. In this w…
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…
Unveiling desert region in inert doublet model assisted by Peccei-Quinn symmetry
Anupam Ghosh, Partha Konar
The Inert Higgs Doublet model (IDM), assisted by Peccei-Quinn (PQ) symmetry, offers a simple but natural framework of a dark sector that accommodates Weakly Interacting Massive Par…
