Viability of post-inflationary freeze-in with precision cosmology

Anirban Biswas, Sougata Ganguly, Dibyendu Nanda +1

Prediction of inflationary observables from the temperature fluctuation of Cosmic Microwave Background (CMB) can play a pivotal role in predicting the reheating dynamics in the ear…

Probing low scale leptogenesis through gravitational wave

Anirban Biswas, Sougata Ganguly

The quest for a common origin of neutrino mass and baryogenesis is one of the longstanding goals in particle physics. A minimal gauge extension of the Standard Model by $U(1)_{\rm…

Can leptophilic-ALP be a solution to the muon anomaly?

Sougata Ganguly, Biswarup Mukhopadhyaya, Sourov Roy

In the light of recent measurement of muon , we investigate the phenomenological implications of an axion-like particle (ALP) which only couples to the standard model charge…

Non-adiabatic evolution of dark sector in the presence of gauge symmetry

Ananya Tapadar, Sougata Ganguly, Sourov Roy

In secluded dark sector scenario, the connection between the visible and the dark sector can be established through a portal coupling and its presence opens up the possibility of n…

When Freeze-out occurs due to a non-Boltzmann suppression: A study of degenerate dark sector

Anirban Biswas, Sougata Ganguly, Sourov Roy

Exponential suppression or commonly known as the Boltzmann suppression in the number density of dark matter is the key ingredient for creating chemical imbalance prior to the usual…
