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…
The fast, the slow and the merging: probes of evaporating memory burdened PBHs
Alessandro Dondarini, Giulio Marino, Paolo Panci +1
The so-called memory-burden effect implies that evaporating Primordial Black Holes (PBHs) inevitably stabilize before complete decay. This stabilization opens a new mass window for…
(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…
Scalar Rayleigh Dark Matter: current bounds and future prospects
Daniele Barducci, Dario Buttazzo, Alessandro Dondarini +4
Dark Matter can interact with electroweak gauge bosons via higher-dimensional operators, in spite of being neutral under gauge interactions, much like neutral atoms interact with p…
