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…
ECFA Higgs, electroweak, and top Factory Study
H. Abidi, J. A. Aguilar-Saavedra, S. Airen +373
The ECFA Higgs, electroweak, and top Factory Study ran between 2021 and 2025 as a broad effort across the experimental and theoretical particle physics communities, bringing togeth…
(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…
Axion Dark Matter from Heavy Quarks
Mohammad Aghaie, Giovanni Armando, Angela Conaci +5
We propose simple scenarios where the observed dark matter abundance arises from decays and scatterings of heavy quarks through freeze-in of an axion-like particle with mass in the…
Neutrino dipole portal at a high energy collider
Daniele Barducci, Alessandro Dondarini
We study the phenomenology of dipole portal operators connecting active and sterile neutrinos at a futuristic muon collider. These operators can be the dominant portal betwee…
Bounds on Ultralight Dark Matter from NANOGrav
Mohammad Aghaie, Giovanni Armando, Alessandro Dondarini +1
The compelling evidence for the detection of the stochastic gravitational wave background by NANOGrav imposes constraints on the mass of compact cores of ultralight dark matter, al…
Causality Bounds in Quadratic Inflation from Purely Virtual Particles
Alessandro Dondarini
The "" slow roll inflation combined with General Relativity is largely excluded by Planck data. In this paper, we consider the same potential combined with the gravity…
