Sažetak
We consider the problem of factorization in B decays and illustrate calculation of nonfactorizable contributions employing the QCD light-cone sum rule method. More detailed we present the calculation of the "charming penguin" contributions as a potential source of the substantial nonfactorizable O(1/mb) effects in the B → π π decay. Although the predicted corrections are not sizable, by calculating the CP asymmetry we illustrate how such corrections can accumulate to a visible effect. In conclusion, nonfactorizable contributions in color-suppressed B decays are briefly discussed.
