Abstract: The extraction of Cabibbo-Kobayashi-Maskawa matrix element information from hadronic B decays generally suffers from discrete ambiguities, hampering the diagnosis of physics beyond the standard model. We show that a measurement of the rate asymmetry, which is CP violating, in B±→ρ±ρ0(ω)→ρ±π+π-, where the invariant mass of the π+π- pair is in the vicinity of the ω resonance, can remove the mod(π) uncertainty in α≡arg[-VtdVtb*/(VudVub*)] present in standard analyses.
