Ruling out light axions: the writing is on the wall
Konstantin A. Beyer, Subir Sarkar
We revisit the domain wall problem for QCD axion models with more than one quark charged under the Peccei-Quinn symmetry. Symmetry breaking during or after inflation results in the…

Parametric co-linear axion photon instability
K. A. Beyer, G. Marocco, C. Danson +2
Axions and axion-like particles generically couple to QED via the axion-photon-photon interaction. This leads to a modification of Maxwell's equations known in the literature as ax…

Axion-like-particle decay in strong electromagnetic backgrounds
B. King, B. M. Dillon, K. A. Beyer +1
The decay of a massive pseudoscalar, scalar and U(1) boson into an electron-positron pair in the presence of strong electromagnetic backgrounds is calculated. Of particular interes…
