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…
Imprints of MeV Scale Hidden Dark Sector at Planck Data
Sougata Ganguly, Sourov Roy, Abhijit Kumar Saha
New light species can contribute to the number of effective relativistic degrees of freedom () at Cosmic Microwave Background (CMB) which is precisely measured by Plan…
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…
