Hadronic B decay at BELLE and BABAR

Abstract

There are several exciting results for the hadronic B decays of Belle and BaBar recently. My report focuses on the ratios of branching fractions and $CP$ asymmetry for $B \to hh$ decays at Belle and BaBar where $h$ denotes $π$ or $K$. The observations of $B^+ \to K^+ \bar{K}{}^0$, $B^0 \to K^0 \bar{K}{}^0$ are published both by Belle and BaBar and shown here. We also report the observation of $B^+ \to ρ^+ K^0$ and search of $B^+ \to \bar{K}{}^{* 0} K^+$, $B^0 \to ρ^0 ρ^0$, $B^0 \to a_0^- π^+$ and $B^0 \to a_0^- K^+$ at BaBar. Finally, we will show the results of amplitude analysis of the decays $B^0 \to ϕK^*_2(1430)^0$, $ϕK^*(892)^0$ and $ϕ(Kπ)^0_{\rm S-wave}$ at BaBar.}
