Abstract

I report results on $B\to VV$ and $B\to PV$ decays. The results include the measurements of the decay amplitudes and the branching fractions in the decays $B\to \phi K^*$ and $B^+\to \rho^+\rho^0$, the measurements of the branching fraction and CP asymmetry in $B^+\to \rho^+\pi^0$, and the first evidence of the decay $B^0\to\rho^0\pi^0$.
