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…
Impact of Non-Thermal Leptogenesis with Early Matter Domination on Gravitational Waves from First-order Phase Transition
Dilip Kumar Ghosh, Anish Ghoshal, Koustav Mukherjee +2
We study the impact of non-thermal leptogenesis on the spectrum of gravitational waves (GWs) produced by a strong first-order phase transition in the early Universe. We consider a…
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…
Electroweak Phase Transition in Two Scalar Singlet Model with pNGB Dark Matter
Dilip Kumar Ghosh, Koustav Mukherjee, Shourya Mukherjee
We investigate the dynamics of the electroweak phase transition within an extended Standard Model framework that includes one real scalar and one complex scalar , both o…
