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,…

Leptophilic ALPs in Laboratory Experiments
Alexander Eberhart, Marco Fedele, Felix Kahlhoefer +2
We study the collider phenomenology of leptophilic axion-like particles (ALPs), i.e. pseudoscalar particles that couple only to charged leptons. Loops of charged leptons induce eff…

Supernova limits on 'QCD axion-like particles'
Alessandro Lella, Eike Ravensburg, Pierluca Carenza +1
In this paper, we explore the phenomenology of massive Axion-Like Particles (ALPs) coupled to quarks and gluons, dubbed 'QCD ALPs', with an emphasis on the associated low-energy ob…
