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

The difference between the CP asymmetries of the $B^0\to K^{+}{\pi }^{-}$ and $B^+ \to K^+ \pi^0$decayshasbeenrecentlyconfirmedwithanevidencelargerthan$5\sigma$'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.
