Gravitational wave pathway to testable leptogenesis

A Dasgupta, PSB Dev, A Ghoshal, A Mazumdar - Physical Review D, 2022 - APS
We analyze the classically scale-invariant BL model in the context of resonant leptogenesis
with the recently proposed mass-gain mechanism. The BL symmetry breaking in this …

Maximizing direct detection with highly interactive particle relic dark matter

G Elor, R McGehee, A Pierce - Physical Review Letters, 2023 - APS
We estimate the maximum direct detection cross section for sub-GeV dark matter (DM)
scattering off nucleons. For DM masses in the range 10 keV–100 MeV, cross sections …

A bstract We present an updated analysis of the first-order phase transition associated with
symmetry breaking in the early Universe in a classically scale-invariant model extended with …

Axion-like particle (ALP) portal freeze-in dark matter confronting ALP search experiments

DK Ghosh, A Ghoshal, S Jeesun - Journal of High Energy Physics, 2024 - Springer
A bstract The relic density of Dark Matter (DM) in the freeze-in scenario is highly dependent
on the evolution history of the universe and changes significantly in a non-standard (NS) …

Signatures of non-thermal dark matter with kination and early matter domination. Gravitational waves versus laboratory searches

A Ghoshal, L Heurtier, A Paul - Journal of High Energy Physics, 2022 - Springer
A bstract The non-thermal production of dark matter (DM) usually requires very tiny
couplings of the dark sector with the visible sector and therefore is notoriously challenging to …

Probing freeze-in dark matter via heavy neutrino portal

B Barman, PSB Dev, A Ghoshal - Physical Review D, 2023 - APS
We explore the possibility of probing freeze-in dark matter (DM) produced via the right-
handed neutrino (RHN) portal using the RHN search experiments. We focus on a simplified …

Probing pre-BBN era with scale invariant FIMP

B Barman, A Ghoshal - Journal of Cosmology and Astroparticle …, 2022 - iopscience.iop.org
Detecting dark matter (DM) relic via freeze-in is difficult in laboratories due to smallness of
the couplings involved. However, a non-standard cosmological history of the Universe, prior …

A bstract FASER, the ForwArd Search ExpeRiment, is a currently operating experiment at
the Large Hadron Collider (LHC) that can detect light long-lived particles produced in the …

Vector dark matter in supercooled Higgs portal models

MT Frandsen, ME Thing, M Heikinheimo, K Tuominen… - Physical Review D, 2023 - APS
We consider extensions of the Standard Model by a hidden sector consisting of a gauge
field coupled with a scalar field. In the absence of dimensionful parameters in the tree-level …
