Constraints upon the CKM angle phi2 (alpha) from Belle and BaBar
A. J. Schwartz
Abstract
The Belle and BaBar experiments have measured branching fractions and CP asymmetries in the charmless decay modes B0->pi+pi-, B0->rho+pi-/rho-pi+, and B0->rho+rho-. From these measurements, constraints upon the CKM angle phi2 can be obtained. These constraints consistently indicate that phi2 is around 100 degrees.
