Minimal Proton-Mass Dark Matter
Majed Khalaf, Eric Kuflik, Alessandro Lenoci +2
We present a minimal dark matter scenario: a single complex scalar carrying baryon and lepton number, with no new exact stabilizing symmetry. Its leading interaction is a dimension…
Millicharged Particle Constraints from Asymptotic Giant Branch Stars
Damiano F. G. Fiorillo, Giuseppe Lucente, Jeremy Sakstein +1
We investigate the effect of millicharged particles (MCPs) with electric charge and mass on the late-stage evolution phases of low-mass stars in globular clusters.…
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…
Magnetic Turbulence Boosts Supernova Signals of Axion-Photon Conversion
Damiano F. G. Fiorillo, Ãngel Gil Muyor, Georg G. Raffelt +1
Magnetic fields between a supernova (SN) and Earth convert axions into gamma rays. The absence of such a signal in coincidence with SN 1987A neutrinos, using the coherent Milky Way…
Stripped-Envelope Supernovae for QCD Axion Detection
Francisco R. Candón, Damiano F. G. Fiorillo, Ãngel Gil Muyor +3
QCD axions would be copiously produced in the proto-neutron star formed in a core-collapse supernova (SN). After escaping, they would convert into gamma rays in the Galactic magnet…
