B → K π puzzle and new sources of CP violation in supersymmetry

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. © 2009 Elsevier B.V. All rights reserved.
