David Miller (UChicago) "A new paradigm for axion discovery: From broadband direct detection to collider interpretations"
I will describe a comprehensive physics program to discover axions and axion-like particles, their supersymmetric counter-parts, and even dark photons using both direct detection approaches and collider experiments. In particular, I will describe the BREAD experiment, which is a novel dish antenna design led by Fermilab and UChicago for detecting broadband ~ueV-eV axions and wave-like dark matter. I will discuss the motivation for this new detector design, and the progress towards first stage dark photon and axion pilot experiments for two distinct frequency ranges - GigaBREAD and InfraBREAD - with expected sensitivities to unexplored coupling strengths. I will also describe our R&D program for reflector characterization, horn antenna & sensor testing, and signal readout. Lastly, I will describe new phenomenological considerations and experimental approaches for axion and axino -- the supersymmetric axion counterpart -- searches at colliders.
