Stacking the Deck: Gambling on a Light QCD Axion
Abhishek Banerjee, Manuel A. Buen-Abad, Anson Hook
We consider axions lighter than what their QCD couplings might otherwise suggest. Starting with a -axion, we introduce a small explicit symmetry-breaki…
Warm Inflation with Pseudo-scalar Couplings
Edward Broadberry, Anson Hook, Sagnik Mondal
Inflaton couplings during warm inflation result in the production of a thermal bath. Thermal friction and fluctuations can dominate the standard de Sitter analogues, resulting in a…
Predicting the Dark Matter -- Baryon Abundance Ratio
Abhishek Banerjee, Dawid Brzeminski, Anson Hook
We discuss relaxation solutions to the dark matter - baryon coincidence problem in the context of QCD axion dark matter. In relaxation solutions, a moduli dynamically adjusts the m…
Searching for String Bosenovas with Gravitational Wave Detectors
Dawid Brzeminski, Anson Hook, Junwu Huang +1
We study the phenomenology of string bosenova explosions in vector superradiance clouds around spinning black holes, focusing on the observable consequences in gravitational wave d…
A Closer Look in the Mirror: Reflections on the Matter/Dark Matter Coincidence
Arushi Bodas, Manuel A. Buen-Abad, Anson Hook +1
We argue that the striking similarity between the cosmic abundances of baryons and dark matter, despite their very different astrophysical behavior, strongly motivates the scenario…
A Dynamical Explanation of the Dark Matter-Baryon Coincidence
Dawid Brzeminski, Anson Hook
The near equality of the dark matter and baryon energy densities is a remarkable coincidence, especially when one realizes that the baryon mass is exponentially sensitive to UV par…
Long-Lived Particles at the Energy Frontier: The MATHUSLA Physics Case
David Curtin, Marco Drewes, Matthew McCullough +85
We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a comprehensive survey of Standard Model (SM) extensions. LLPs are a common prediction of…
