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.

Discussion (0). Continue with ORCID to comment.

    A new dimension-seven operator is generated by the gluon equation of motion in the presence of the axion-gluon coupling, and its spectator-scattering contribution to B to K a is roughly 25 percent of the soft-overlap ...

    hep-ph 2026-06 unverdicted novelty 6.0 of 10

    A unitarized FSI framework with no adjustable parameters for B decays, calibrated on BaBar γγ o D Dbar data, predicts enhanced CP asymmetries in pure-annihilation channels that match existing measurements.
