Scientific paper

We discuss a possibility of large electroweak(EW) penguin contribution in B-->K pi and pi pi. The recent experimental data may be still suggesting that there are some discrepancies between the data and theoretical estimations. In B --> K pi decays, to explain several theoretical relations among the branching ratios, a slightly large electroweak penguin contribution and large strong phase differences or quite large color suppressed tree contribution seem to be needed. The contributions should appear also in B --> pi pi. We show, as an example, a solution to solve the discrepancies in both B --> K pi and B --> pi pi. It may be suggesting to need the large electroweak penguin contribution with new weak phases and some SU(3) breaking effects by new physics in both QCD and electroweak penguin type processes.
