Estimate of Charming Penguins in B -> pi pi
We consider the problem of factorization in B decays and illustrate the calculation of nonfactorizable contributions employing the QCD light-cone sum rule method. We present a more detailed calculation of the "charming penguin" contributions as a potential source of the substantial nonfactorizable O(1/m_b) effects in the B -> pi pi 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 nonleptonic B decays into charmonium are briefly discussed.
