Solving the strong CP problem with supersymmetry

Abstract

We propose a new solution to the strong CP problem based on supersymmetric non-renormalization theorems. CP is broken spontaneously and it's breaking is communicated to the MSSM by radiative corrections. The strong CP phase is protected by a susy non-renormalization theorem and remains exactly zero while loops can generate a large CKM phase from wave function renormalization. We present a concrete model as an example but stress that our framework is general. We also discuss constraints on susy breaking and point out experimental signatures.
