Abstract

We offer a new solution to an old puzzle in the penguin-dominated B→πK decays. The puzzle is the inconsistency among the measurements of the branching ratios and CP asymmetries of the four B→πK decays: B+→π+K0, B+→π0K+, Bd0→π−K+, Bd0→π0K0. We solve the B→πK puzzle by considering the effect of an axionlike particle (ALP) that mixes with the π0 and has mass close to the π0 mass. We show that the ALP can also explain the anomalies in the electron and muon anomalous magnetic moments.
