Abstract
Affleck-Dine (AD) baryogenesis is compelling yet challenging to probe because of the high-energy physics involved. We demonstrate that this mechanism can be generically realized with low-energy new physics, without supersymmetry, while producing detectable gravitational waves (GWs) sourced by the parametric resonance of a light scalar field. In viable models, the scalar has a mass of GeV, yielding GWs with peak frequencies of Hz. This study further reveals a new complementarity between upcoming LIGO-frequency GW detectors and laboratory searches across frontiers of particle physics.
