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…
Prediction for Maximum Supercooling in SU(N) Confinement Transition
Prateek Agrawal, Gaurang Ramakant Kane, Vazha Loladze +1
The thermal confinement phase transition (PT) in Yang-Mills theory is first-order for , with bounce action scaling as . Remarkably, lattice data for the actio…
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.…
