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…
Ultralight Dilatonic Dark Matter
Abhishek Banerjee, Csaba Csáki, Michael Geller +2
The dilaton, a pseudo-Nambu-Goldstone boson (pNGB) of broken scale invariance, is an appealing ultralight dark matter (DM) candidate. Its mass is protected by conformal invariance…
Dynamical Axion Misalignment from the Witten Effect
Abhishek Banerjee, Manuel A. Buen-Abad
We propose a relaxation mechanism for the initial misalignment angle of the pre-inflationary QCD axion with a large decay constant. The proposal addresses the challenges posed to t…
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…
