Freeze-in vector dark matter at low reheating temperature
Dilip Kumar Ghosh, Sourav Gope, Xiao-Gang He +2
The freeze-in mechanism for dark matter (DM) requires extremely feeble interactions with the Standard Model (SM), preventing thermal equilibrium in the early Universe and typically…
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…
Cosmological implications of inflaton-mediated dark and visible matter scatterings after reheating
Deep Ghosh, Sourav Gope, Satyanarayan Mukhopadhyay
The initial density of dark matter (DM) particles, otherwise secluded from the standard model (SM), may be generated at reheating, with an initial temperature ratio for internal th…
Cannibal dark matter decoupled from standard model: cosmological constraints
Avirup Ghosh, Sourav Gope, Satyanarayan Mukhopadhyay
An internally thermalized dark matter (DM) with only gravitational interaction with the standard model (SM) particles at low temperatures, may undergo number-changing self-scatteri…
