Natural Kobayashi-Maskawa Model of CP Violation and Flavor Physics
arXiv:hep-ph/0403070
Abstract
We explore the possible tie between the naturalness of having a very small strong CP $θ$ parameter in the Kobayashi-Maskawa Model and the flavor symmetry. We provide many examples in which the flavor symmetry group at high energy can naturally give rise to Kobayashi-Maskawa Model at low energy with a naturally small theta.
