Results on ϕ2 from e+e- colliders
Year: 2013
Type: preprint
Abstract: We present a summary of measurements sensitive to the CKM angle ϕ2 (α), performed by the BaBar and the Belle experiments which both collect B\bar{B} pairs produced at the Υ(4S) resonance in asymmetric e+e- collisions. We discuss the decays B -> ππ, ρρ, a_1πand (ρπ)^0. The CP asymmetries, branching fractions and polarizations obtained are used to constrain ϕ2.
