Charmless hadronic B decays

Abstract

This proceeding covers recent measurements of charmless hadronic B decays such as (equation presented) reported from Belle, BaBar and LHCb experiments. In the (equation presented) decay channel, Belle found a 2.7σ excess of signal, which correspond to the branching fraction (equation presented) and the longitudinal polarization fraction fL = 1.06±0.30±0.14. In BaBar, the B0 → ωω is measured with the (eqation presented) and the B upper limit of B0 → ωφ is set to 0.7 × 10-6 at the 90% confidence-level. Belle reports an updated measurement of (equation presentred) in the B0 → π0π0 and the first measurement of (equation presented) in B0 → ηπ0. The (equation presented) and the (equation presented) are precisely measured by LHCb, where the B last uncertainty is due to the B0 → φK∗0 reference mode. Finally the difference between CP asymmetries of K∗π intermediate states is reported as (equation presented) by BaBar. © Copyright owned by the author(s) under the terms of the Creative Commons.
