Stripped-Envelope Supernovae for QCD Axion Detection
Francisco R. Candón, Damiano F. G. Fiorillo, Ángel 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…
Small Progenitors, Large Couplings: Type Ic Supernova Constraints on Radiatively Decaying Particles
Francisco R. Candón, Damiano F. G. Fiorillo, Hans-Thomas Janka +2
Supernova (SN) 1987A provides classic bounds on gamma-ray flashes from the radiative decay of sub-GeV particles, but the latter may decay so rapidly as to be shielded by the stella…
Axion-photon conversion in transient compact stars: Systematics, constraints, and opportunities
Damiano F. G. Fiorillo, Ángel Gil Muyor, Hans-Thomas Janka +2
We study magnetic conversion of ultra-relativistic axion-like particles (ALPs) into photons in compact-star environments, focusing on the hot, transient conditions of core-collapse…
Leading bounds on micro- to picometer fifth forces from neutron star cooling
Damiano F. G. Fiorillo, Alessandro Lella, Ciaran A. J. O'Hare +1
The equivalence principle and the inverse-square law of gravity could be violated at short distances ( to meters) by scalars sporting a coupling to nucleo…
Exploring the Dark Universe: A European Strategy for Axions and other WISPs Discovery
Deniz Aybas, Francesca Calore, Michele Cicoli +17
Axions and other very weakly interacting slim (with 1 GeV) particles (WISPs) are a common feature of several extensions of the Standard Model of Particle Physics. The search…
Supernova production of axion-like particles coupling to electrons, reloaded
Damiano F. G. Fiorillo, Tetyana Pitik, Edoardo Vitagliano
We revisit the production of axion-like particles (ALPs) coupled to electrons at tree-level in a relativistic plasma. We explicitly demonstrate the equivalence between pseudoscalar…
