Abstract

The difference between the CP asymmetries of the B⁰ → K⁺ π^- and B⁺ → K⁺ π⁰ decays has been recently confirmed with an evidence larger than 5σ'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.
