Inelastic Dark Matter from a Higher-Dimensional Operator: The LUX-ZEPLIN High-Recoil Event and Thermal Relic
Debajyoti Choudhury, Jaydeb Das, Divya Sachdeva
The recent LUX-ZEPLIN (LZ) data shows a nuclear-recoil event around , motivating scenarios in which dark matter (DM) preferentially scatters at large recoil ener…
Connecting Vector-like Muons, pNGB Dark Matter and Electroweak Phase Transition through Collider and Gravitational Wave
Jaydeb Das, Saurabh Niyogi, Amir Subba
We study an extension of the Standard Model with two complex scalar singlets, and , charged under and , respectively, and a muon-philic vect…
From Thermal History to Multi-Messenger Signatures in Symmetric Dark Sector
Debajyoti Choudhury, Jaydeb Das, Divya Sachdeva
We investigate a -symmetric extension of the Standard Model consisting of a right-handed neutrino (), a dark fermion () that dominates the relic density and a…
A Non-Holomorphic Modular Framework for Resonant Leptogenesis with Gravitational Wave Signatures
Mitesh Kumar Behera, Jaydeb Das, Niloy Mondal
We study a type-I seesaw framework based on non-holomorphic modular symmetry, where polyharmonic Maaß forms construct the Yukawa couplings and right-handed neutrino (RHN) Maj…
Solving Cosmological Puzzles using Finite Temperature SMEFT
Debajyoti Choudhury, Jaydeb Das, Tripurari Srivastava
We study a minimal framework that naturally yields viable Dark Matter, a strong first-order electroweak phase transition and low-scale resonant leptogenesis. Augmenting the Standar…
Revisiting Singlet Fermion Dark Matter with a Scalar Portal: Connecting Higgs Phenomenology and Strong Electroweak Phase Transition
Jaydeb Das, Saurabh Niyogi, Tripurari Srivastava
We investigate a minimal extension of the Standard Model with a real singlet scalar and a singlet Dirac fermion acting as dark matter. Unlike a conventional singlet scalar setup, w…
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…
Two-loop dimension Six Effective Action: Integrating Out Heavy Scalar
Nilabhra Adhikary, Jaydeb Das, Debmalya Dey
For the first time, we present the model-independent two-loop effective action up to dimension six after integrating out heavy scalar(s) employing the Heat-Kernel method. We comput…
