Enlightening dark moments of neutrino with superradiance
Indra Kumar Banerjee, Ujjal Kumar Dey, Anna John
Neutrinos can acquire electromagnetic moments either within the Standard Model through higher order radiative corrections or within the domain of new physics. In this study we focu…
Gravitational Wave Probe of Singlet-Doublet Dark Matter Induced Radiative Neutrino Mass
Ujjal Kumar Dey, Santu Kumar Manna, Partha Kumar Paul +2
We investigate an one loop radiative neutrino mass model, where the loop particles, notably a singlet fermion (), a doublet fermion () and three generations of singlet scal…
Asymmetric Cannibal Dark Matter: Constraints from Neutron Star
Ujjal Kumar Dey, Sourav Gope
Asymmetric dark matter can be efficiently captured by neutron stars via elastic scattering with nucleons and dark matter self scattering. The accumulated dark matter thermalizes an…
Stodolsky effect in the framework of Generalised Neutrino Interactions
Siddhartha Bandyopadhyay, Ujjal Kumar Dey
We study the Stodolsky effect utilizing the most general form of neutrino interactions with electrons below the electroweak scale by considering all possible Lorentz invariant oper…
Majorana CP Violation Insights from Decaying Neutrinos
Sabila Parveen, Soumya Bonthu, Newton Nath +2
It is well-known that within the standard three flavor neutrino oscillation formalism, the Majorana phases appearing in the neutrino mixing matrix cannot have any effect on neutrin…
Mini-review on the production of Primordial Black Holes from First-Order Phase Transitions in the Early Universe
Indra Kumar Banerjee, Ujjal Kumar Dey, Shaaban Khalil
We review the creation mechanism of primordial black holes from first order phase transitions. We discuss various model-dependent and independent mechanisms and relate the properti…
