Generalized Uncertainty Principle as a Mechanism for CP Violation

Abstract

Within quantum electrodynamics we show that the Generalized Uncertainty Principle induces higher-derivative corrections that promote the topological invariant $F_{\mu \nu }{\tilde{F}}^{\mu \nu }$ to the dynamical, non-topological operator ${\partial }^{\lambda }{F}_{\mu \nu }{\partial }_{\lambda }{\tilde{F}}^{\mu \nu }$. We explore the resulting phenomenology, focusing on the generation of electric dipole moments. Our findings open a new low-energy window for testing quantum-gravity scenarios through precision measurements of charge-parity violation.
