Anatomy of Prominent B and K Decays and Signatures of CP-Violating New Physics in the Electroweak Penguin Sector / Buras, Andrzej J (Tech. Univ. München) ; Fleischer, Robert (CERN) ; Recksiegel, Stefan (Tech. Univ. München) ; Schwab, Felix (Tech. Univ. München and MPI München)
The recent observation of B_d -> pi^0 pi^0 at the B factories with a surprisingly large branching ratio represents a challenge for theory, and complements the amazingly small B_d -> pi^+ pi^- rate. We point out that all puzzling B -> pi pi features can be accommodated in the Standard Model (SM) through non-factorizable hadronic interference effects, extract the relevant parameters, and predict the CP asymmetries of B_d -> pi^0 pi^0.
