On the decay of a light spinless particle into two photons
Ferruccio Feruglio, Gabriele Levati, Robert Ziegler
We analyze the effective couplings of a light, spinless, gauge-singlet particle to on-shell photons. Starting from the most general theory at the electroweak scale, which allow…

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…
