$B\to \pi \rho$, $\pi \omega$ Decays in Perturbative QCD Approach

Cai-Dian Lü, Mao-Zhi Yang

We calculate the branching ratios and CP asymmetries for $B^0\to {\pi }^{+}{\rho }^{-}$, $B^0\to {\rho }^{+}{\pi }^{-}$, $B^{+}\to {\rho }^{+}{\pi }^0$, $B^{+}\to {\pi }^{+}{\rho }^0$, $B^0\to {\pi }^0{\rho }^0$, $B^{+}\to {\pi }^{+}\omega$ and $B^0\to {\pi }^0\omega$…
