Abstract

Expressions for decay amplitudes of B0, B- and Bs mesons to two light pseudoscalar or vector mesons, including isosinglet mesons eta, eta', omega, phi, are obtained using Soft Collinear Effective Theory at LO in 1/mb. These are then used to predict unmeasured branching ratios, direct and indirect CP asymmetries in B0, B- and Bs decays into two light pseudoscalars, following a determination of nonperturbative SCET parameters from existing data using a chi-squared fit. A separate discussion of indirect CP asymmetries in penguin dominated B0 --> eta' K(S/L), pi0 K(S/L) decays is given.
