Testing unification and the heterotic string with the axion-photon coupling

04.12.2025 10:30 – 11:30

The topological nature of axion couplings to gauge bosons offers unique opportunities to obtain information about the UV limit of the SM. I will discuss why the discovery of an axion-like particle above the QCD line would rule out grand unified theories and the perturbative heterotic string. Based on 2206.07053, 2410.03820 and 2509.08042.
