CP Violation via $\rho \omega$ Interference

Abstract

We consider $B^{\pm ,0}\to {\rho }^0(\omega )h^{\pm ,0}$, where ${\rho }^0(\omega )$ decays to ${\pi }^{+}{\pi }^{-}$ and $h$ is any hadronic final state, such as $\pi$ or $K$. We find a large direct CP asymmetry in B-meson decays via $\rho \omega$ interference. A possible method to determine weak phases, such as ${\varphi }_{2,3}$, is discussed. The experimental feasibility is also shown.
