Title: Testing the Heterotic String and F-theory GUTs with Axions
Speaker: Mario Reig (CERN)
Venue & Time: Red Room / 15:00
Abstract: 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, both in 4 dimensions and in higher-dimensions, and the perturbative Heterotic String. Based on 2206.07053, 2410.03820, 2509.08042, and 2606.09982.
