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…
Axion-Like Electrophilic Portal for Pion Dark Matter
Vincenzo Fiorentino, Ji-Heng Guo, Giacomo Landini +1
We investigate a scenario where Strongly Interacting Massive Particle (SIMP) dark matter interacts with an axion-like particle (ALP) that couples exclusively to electrons. This min…
Do Finite Density Effects Jeopardize Axion Nucleophobia in Supernovae?
Luca Di Luzio, Vincenzo Fiorentino, Maurizio Giannotti +2
Nucleophobic axion models, wherein axion couplings to both protons and neutrons are simultaneously suppressed, can relax the stringent constraints from SN 1987A. However, it remain…
