Space-like Penguin Effects in $B \to PP$ Decays

High Energy Physics - Phenomenology 2009-10-28 v2

Abstract

The space-like penguin contributions to branching ratios and CP asymmetries in charmless decays of BB to two pseudoscalar mesons are studied using the next-to-leading order low energy effective Hamiltonian. Both the gluonic penguin and the electroweak penguin diagrams are considered. We find that the effects are significant.
