Large electroweak penguins in B --> pi pi and B --> pi K : implication for new physics

Soumitra Nandi, Anirban Kundu

We show that the anomalies in the $B\to \pi \pi$ decay channels, {\em viz.}, the large branching ratio of $B\to {\pi }^0{\pi }^0$ and large direct CP asymmetry of $B\to {\pi }^{+}{\pi }^{-}$, can both be explaine…
