Complex Scalar Singlet Model: Electroweak Phase Transition and Gravitational Waves
Dilip Kumar Ghosh, Debadrita Mukherjee, Koustav Mukherjee +1
The Standard Model (SM) cannot explain the observed baryon asymmetry of the Universe (BAU), thus driving the need for physics beyond the SM, which can generate the electroweak bary…
Cogenesis of visible and dark matter in a scotogenic model
Debajit Bose, Rohan Pramanick, Tirtha Sankar Ray
Within a scotogenic neutrino mass model we explore the cogenesis of matter from the CP violating decay of a heavy -odd right handed neutrino that simultaneously popul…
Neutrinos from captured dark matter in galactic stars
Debajit Bose, Rohan Pramanick, Tirtha Sankar Ray
Sub-GeV neutrinos produced in a stellar core may emerge from main sequence stars, white dwarfs and brown dwarfs producing possible observable signals of dark matter capture. A dist…
Towards a more complete description of hybrid leptogenesis
Rohan Pramanick, Tirtha Sankar Ray, Arunansu Sil
Hybrid leptogenesis framework combining type I and type II seesaw mechanism for neutrino mass necessarily include scattering topologies involving both the scalar triplet and the ri…
Neutrino mass and leptogenesis in a hybrid seesaw model with a spontaneously broken CP
Rohan Pramanick, Tirtha Sankar Ray, Avirup Shaw
We introduce a novel hybrid framework combining type I and type II seesaw models for neutrino mass where a complex vacuum expectation value of a singlet scalar field breaks CP spon…
Broad toplike vector quarks at LHC and HL-LHC
Sayan Dasgupta, Rohan Pramanick, Tirtha Sankar Ray
Top like vector quarks arising from underlying strong sectors are expected to have large decay widths pushing them beyond the narrow width approximation. In this paper we consider…
Bargmann Invariants, Geometric Phases and Recursive Parametrization with Majorana Fermions
Rohan Pramanick, Swarup Sangiri, Utpal Sarkar
A generalized connection between the quantum mechanical Bargmann invariants and the geometric phases was established for the Dirac fermions. We extend that formalism for the Majora…
