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…
On the Galactic radio signal from stimulated decay of axion dark matter
P. S. Bhupal Dev, Francesc Ferrer, Takuya Okawa
We study the full-sky distribution of the radio emission from the stimulated decay of axions which are assumed to compose the dark matter in the Galaxy. Besides the constant extrag…
Long-lived doubly charged scalars in the left-right symmetric model: catalyzed nuclear fusion and collider implications
Evgeny Akhmedov, P. S. Bhupal Dev, Sudip Jana +1
We show that the doubly charged scalar from the -triplet Higgs field in the Left-Right Symmetric Model has its mass governed by a hidden symmetry so that its value can be…
Explanation of the 95 GeV and excesses in the Minimal Left-Right Symmetric Model
P. S. Bhupal Dev, Rabindra N. Mohapatra, Yongchao Zhang
We propose a simple interpretation of the excesses reported by both CMS and ATLAS groups at 95 GeV together with the LEP excess in the channel around the same ma…
