CP violation in gauge theories

High Energy Physics - Phenomenology 2009-10-31 v2

Abstract

We define the CP transformation properties of scalars, fermions and vectors in a gauge theory and show that only three types of interactions can lead to CP violation: scalar interactions, fermion-scalar interactions and FF~ F \tilde F associated with the strong CP problem and which involve only the gauge fields. For technicolor theories this implies the absence of CP violation within perturbation theory.
