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.…
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…
Heavy QCD Axion at Belle II: Displaced and Prompt Signals
Emilie Bertholet, Sabyasachi Chakraborty, Vazha Loladze +3
The QCD axion is a well-motivated addition to the standard model to solve the strong problem. If the axion acquires mass dominantly from a hidden sector, it can be as heavy…
Heavy QCD Axion in transition: Enhanced Limits and Projections
Sabyasachi Chakraborty, Manfred Kraus, Vazha Loladze +2
We study a "heavy" QCD axion whose coupling to the standard model is dominated by but with . This is well motivated as it can solve the str…
A solar origin of the XENON1T excess without stellar cooling problems
Sabyasachi Chakraborty, Tae Hyun Jung, Vazha Loladze +2
Solar interpretations of the recent XENON1T excess events, such as axion or dark photon emissions from the sun, are thought to be at odds with stellar cooling bounds from the horiz…
