Axion-like particles resolve the B→π K and g-2 anomalies

We offer a new solution to an old puzzle in the penguin-dominated B → π K decays. The puzzle is the inconsistency among the measurements of the branching ratios and CP asymmetries of the four B → π K decays : B⁺ → π⁺ K⁰ , B⁺ → π⁰ K⁺ , B_d⁰ → π^- K⁺ , B_d⁰ → π⁰ K⁰ . We solve the B → π K puzzle by considering the effect of an axion-like 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.
