The difference between the CP asymmetries of the B0 ! K+− and B+ ! K+0 decays has been recently confirmed with an evidence larger than 5’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.

Abstract
The difference between the CP asymmetries of the B0 ! K+− and B+ ! K+0 decays has been recently confirmed with an evidence larger than 5’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.File in questo prodotto:
