Abstract

The extraction of CKM-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[−Vtd*Vtb/(VudVub*)] present in standard analyses.
