Self-Interaction Bounds on Ultralight Dark Matter Couplings to Matter
Mohammad Aghaie, Shao-Ping Li
Ultralight dark matter (ULDM) couplings to matter fields and ULDM self-interactions are typically treated as independent probes. However, since the ULDM-matter couplings unavoidabl…

Minimal Dark Matter in the sky: updated Indirect Detection probes
Mohammad Aghaie, Alessandro Dondarini, Giulio Marino +1
Minimal Dark Matter is among the simplest and most predictive Dark Matter frameworks, with the Majorana SU(2) 5-plet as its smallest accidentally stable real representation. We pre…

(H)ALPing the 511 keV line: A thermal DM interpretation of the 511 keV emission
Mohammad Aghaie, Pedro De la Torre Luque, Alessandro Dondarini +3
We propose a novel framework where MeV-scale Dirac Dark Matter annihilates into axion-like particles, providing a natural explanation for the 511 keV gamma-ray line observed in the…
