SN1987A Constraints of Light with Non-Mixing Polarisations
Debottam Das, Purusottam Ghosh, Rahul Puri
The observation of supernova 1987A (SN1987A) provides a unique opportunity to explore new physics beyond the Standard Model (BSM). The production of new particles in the supernova…
A singlet scalar assisted Leptogenesis and Pseudo-Scalar Dark Matter
Dilip Kumar Ghosh, Purusottam Ghosh, Koustav Mukherjee +1
We study the Leptogenesis and Dark Matter in the presence of an extra singlet complex scalar field in an extended discrete symmetry. The vacuum expectation va…
The at CMB challenges light gauge boson scenarios
Dilip Kumar Ghosh, Purusottam Ghosh, Sk Jeesun +1
The relativistic degrees of freedom () is one of the crucial cosmological parameters. The precise measurement of at the time of cosmic microwave backgrou…
Hubble Tension and Cosmological Imprints of Gauge Symmetry: as a case study
Dilip Kumar Ghosh, Purusottam Ghosh, Sk Jeesun +1
The current upper limit on at the time of CMB by Planck 2018 can place stringent constraints in the parameter space of BSM paradigms where their additional interactio…
CMB signature of non-thermal Dark Matter produced from self-interacting dark sector
Dilip Kumar Ghosh, Purusottam Ghosh, Sk Jeesun
The basic idea of this work is to achieve the observed relic density of a non-thermal dark matter(DM) and its connection with Cosmic Microwave Background (CMB) via additional relat…
