Ruling Out Spiky WIMP Dark Matter using Indirect Searches
Dibya S. Chattopadhyay, P. S. Bhupal Dev, Yago Porto
The dark matter (DM) density profile in the innermost region of the Galaxy remains an open question. In particular, while adiabatic growth of the supermassive black hole Sgr A$^\as…

Updated Constraints from Electric Dipole Moments in the MSSM with R-Parity Violation
Wolfgang Altmannshofer, P. S. Bhupal Dev, Amarjit Soni +1
We revisit the electric dipole moments (EDMs) of quarks and leptons in the Minimal Supersymmetric Standard Model (MSSM) with trilinear -parity violation (RPV). In this framework…

Leptogenesis from Dark Matter Coannihilation
Simran Arora, Debasish Borah, Arnab Dasgupta +2
We propose a minimal extension of the type-I seesaw model to realise leptogenesis from the co-annihilation of dark sector particles. The type-I seesaw model is extended with a sing…
