Measurement of alpha/phi2 in Bo --> pi pi, rho pi and rho rho (1101.1720v1)
Published 10 Jan 2011 in hep-ex
Abstract: We present a summary of the measurements of the CKM angle, alpha (phi2), performed by the BaBar and Belle experiments which collect BBbar pairs at the Y(4S) resonance produced in asymmetric e+ e- collisions. We discuss the measurements of the branching fractions and CP asymmetries in the B --> pi pi, rho pi and rho rho final states that lead to constraints on alpha (phi2).
