CP Violation via $ρω$ Interference

Abstract

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