New Frontiers for Physics Beyond the Standard Model
We present three distinct pathways for theory and experiment beyond the Standard Model. First, we propose an experimental design of a laboratory search for axions based on photon regeneration with superconducting RF cavities. We then study a novel production mechanism for ultralight vector dark matter in the early universe based on a parametric resonance instability. Finally, we show that white dwarfs are in fact ideal detectors of ultra-heavy DM over large regions of parameter space.
