BABAR status and prospects for CP asymmetry measurements: sin(2beta+gamma)

Abstract

The recent experimental results on CP violation related to the angles of the Cabibbo-Kobayashi-Maskawa (CKM) unitarity triangle 2beta+gamma are summarized in these proceedings. These results are obtained with approximately 232 million Y4S->BBbar events collected with the BABAR detector at the PEP-II asymmetric-energy B-factory at SLAC. Using the measurements on time-dependent CP asymmetries in B0->D(*)-+pi+- and B0->D-+rho+- decays and theoretical assumptions, one finds |sin(2beta+gamma)|>0.64 (0.40) at 68% (90%) confidence level. The perspectives of sin(2beta+gamma) measurement with B0bar-> D(*)0bar K(*)0 and B0->D(*)-+ a_0(2)+- decay channels are also discussed.
