Probing new fundamental symmetry

Keisuke Harigaya, UChicago

Particle physics aims to uncover the fundamental laws of nature. The Standard Model has been remarkably successful in explaining most of the masses and interactions of known particles, yet it leaves several fundamental questions unanswered, such as the nature of dark matter, the origin of the matter-antimatter asymmetry, and the puzzling absence of CP violation in the strong interaction (the strong CP problem). These mysteries may be resolved through new fundamental symmetries. In this talk, I will discuss how parity and new gauge symmetries can address the strong CP problem and their implications for models of dark matter and the matter-antimatter asymmetry. I will highlight new experimental targets for dark matter searches, the Large Hadron Collider, and electron electric dipole moment experiments, emphasizing the correlations among these signals.
