How invisible can QCD axions be? From Supernova emission to Cherenkov signals
Luca Di Luzio, Vincenzo Fiorentino, Maurizio Giannotti +2
We investigate the scenario of maximally invisible axions, namely QCD axions whose interactions with matter arise exclusively from the irreducible coupling to gluons responsible fo…
Neutron Star Bounds on Muonic Fifth Forces from Picometer to Kilometer Scales
Damiano F. G. Fiorillo, Alessandro Lella, Georg G. Raffelt +2
Experimental searches for fifth forces coupled to muons are fundamentally limited by the scarcity of muons in ordinary matter, whereas neutron stars contain abundant muon populatio…
Production of Leptophilic Bosons in Ultradegenerate Relativistic Matter
Damiano F. G. Fiorillo, Alessandro Lella, Georg G. Raffelt +2
Neutron stars (NSs) are powerful factories for new particles with masses up to the 100 keV range. These compact stars contain significant populations of charged particles, notably…
Multimessenger probes of Axions from Compact Objects
Alessandro Lella
Astrophysics plays a pivotal role in the quest for axions and axion-like particles, offering guidance to experimental efforts and enabling the investigation of axion properties tha…
Lectures on Light Particles and Compact Objects
Alessandro Lella, Jamie McDonald
This document is based on lectures delivered at a recent COSMIC WISPers COST Action training school in Annecy in September 2025. They examine detection of weakly interacting slim p…
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…
