B -> K pi Puzzle and New Sources of CP Violation in Supersymmetry

Abstract

The difference between the CP asymmetries of the $B^0\to K^{+}{\pi }^{-}$ and $B^{+}\to K^{+}{\pi }^0$ decays has been recently confirmed with an evidence larger than $5\sigma$'s. We discuss it as a possible signal of new physics associated with new (large) CP violation in the electroweak penguin contributions. We propose a supersymmetry breaking scheme where such new sources of CP violation occur in the flavor non-universal trilinear scalar couplings.
