Axion couplings in Orbifold GUTs
Prateek Agrawal, Michael Nee, Mario Reig
We consider the coupling of axions to gauge bosons in higher-dimensional Grand Unified Theories (GUT) inspired by string theory constructions with D-branes on orbifold singularitie…
Axion Quality Problem: Keep Calm and Baryon
Prateek Agrawal, Anson Hook, Vazha Loladze +1
Axion models generically suffer from a severe quality problem when coupled to gravity. In this article we provide a very simple model with a high quality axion. The axion is a pseu…
Supercooled Confinement
Prateek Agrawal, Gaurang Ramakant Kane, Vazha Loladze +1
We study general properties of confinement phase transitions in the early universe. An observable gravitational wave signal from such transitions requires significant supercooling.…
Higher Axion Strings
Vazha Loladze, Arthur Platschorre, Mario Reig
We study the minimal requirements to obtain axion strings for axions with exponentially good quality. These ingredients appear in theories where an axion coming from a higher-form…
