How invisible can QCD axions be? From Supernova emission to Cherenkov signals
Luca Di Luzio, Vincenzo Fiorentino, Maurizio Giannotti +2
The paper studies QCD axions that interact only via their gluon coupling, derives constraints from supernova 1987A cooling based on nucleon bremsstrahlung and pion conversion, and…
Axions at the meV Crossroads: Theory, Cosmology, Astrophysics, and Experiments
Michele Cicoli, Francesco D'Eramo, Luca Di Luzio +18
The meV mass range has emerged as a focal point in axion physics, where advances in theory, cosmology, astrophysics, and experimental techniques converge. Axions in this mass range…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
High-quality Peccei-Quinn symmetry from the interplay of vertical and horizontal gauge symmetries
Luca Di Luzio, Giacomo Landini, Federico Mescia +1
We explore a class of axion models where an accidental Peccei-Quinn (PQ) symmetry automatically emerges from the interplay of vertical (grand-unified) and horizonta…
MuCol Milestone Report No. 7: Consolidated Parameters
Rebecca Taylor, Antoine Chancé, Dario Augusto Giove +459
This document is comprised of a collection of consolidated parameters for the key parts of the muon collider. These consolidated parameters follow on from the October 2024 Prelimin…
Hunting for a 17 MeV particle coupled to electrons
Luca Di Luzio, Paride Paradisi, Nudzeim Selimovic
We discuss a set of precision observables that can probe the existence of a light particle coupled to electrons in the mass range of 1-100 MeV. As a case study, we consider the…
