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 $\pi$ 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 $B^+ \to \rho^+ K^0$ and search of $B^+ \to \bar{K}{}^{* 0} K^+$, $B^0 \to \rho^0 \rho^0$, $B^0 \to a_0^- \pi^+$ and $B^0 \to a_0^- K^+$ at BaBar. Finally, we will show the results of amplitude analysis of the decays $B^0 \to \phi K^*_2(1430)^0$, $\phi K^*(892)^0$ and $\phi (K\pi)^0_{\rm S-wave}$ at BaBar.}
