Direct CP violation in B → Kπ decay has emerged at −10% level, but the asymmetry in B → Kπ mode is consistent with zero. This difference points towards possible New Physics in the electroweak penguin operator. We point out that a sequential fourth generation, with sizable V ∗ t′sVt′b and near maximal phase, could be a natural cause. We use the perturbative… CONTINUE READING
