Title: ν solution to the strong C P problem

Abstract

We present a new solution to the strong CP problem in which the imaginary component of theup quark mass,I[mu], acquires a tiny, but non-vanishing value. This is achieved via a Dirac seesawmechanism, which is also responsible for the generation of the small neutrino masses. Consistencywith the observed value of the up quark mass is achieved via instanton contributions arising fromQCD-like interactions. In this framework, the value of the neutron electric dipole moment is directlyrelated toI[mu], which, due to its common origin with the neutrino masses, implies that the neutronelectric dipole moment is likely to be measured in the next round of experiments. We also presenta supersymmetric extension of this Dirac seesaw model to stabilize the hierarchy among the scalarmass scales involved in this new mechanism
