ALP couplings to muons and electrons: a comprehensive analysis of supernova bounds

Ricardo Z. Ferreira, M. C. David Marsh, Eike Ravensburg

We provide a comprehensive analysis of the phenomenology of axion-like particles (ALPs) produced in core-collapse supernovae (ccSNe) through interactions with electrons and muons,…
