Boosted Dark Matter Driven by Cosmic Rays and Diffuse Supernova Neutrinos
Dilip Kumar Ghosh, Tushar Gupta, Matti Heikinheimo +2
Direct detection of light dark matter can be significantly enhanced by up-scattering of dark matter with energetic particles in the cosmic ambient. This boosted dark matter flux ca…
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…
Exploring the Dark Sector of the inspired FNSM at the LHC
Amit Chakraborty, Dilip Kumar Ghosh, Najimuddin Khan +1
We establish the possibility of having a pseudo-Nambu-Goldstone boson (pNGB) Dark Matter (DM) candidate in the inspired Froggatt-Nielsen Singlet Model (iFNSM) wherein a direct conn…
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…
