Charmless 2- and 3-body B decays and the angle alpha (phi2)
We present preliminary measurements of branching fractions and CP-asymmetry parameters in two- and three-body charmless hadronic B decays. The available data sample consists of 227 million Upsilon(4S) B decays collected with the BABAR detector at the PEP-II asymmetric-energy e+e- collider at SLAC. W...

| Abstract | We present preliminary measurements of branching fractions and CP-asymmetry
parameters in two- and three-body charmless hadronic B decays. The available
data sample consists of 227 million Upsilon(4S) B decays collected with the
BABAR detector at the PEP-II asymmetric-energy e+e- collider at SLAC. We
establish the observation of the decays B --> pi0 pi0 and B0 --> K0K0bar and
constrain the CKM angle alpha with a full SU(2) isospin analysis in the B -->
pi pi system and with a B0 --> pi+ pi- pi0 time-dependent Dalitz plot analysis. |
