We analyze the 5{sigma} difference between the CP asymmetries of the B{sup 0{yields}}K{sup +{pi}-} and B{sup +{yields}}K{sup +{pi}0} decays within the soft collinear effective theory. We find that in the standard model, such a big difference cannot be achieved. We classify then the requirements for the possible New Physics models, which can be responsible for the experimental results. As an example of a New Physics model we study minimal supersymmetric models, and find that the measured asymmetry can be obtained with nonminimal flavor violation.
