  • 摘要:Using 22.7M B B events collected with the BABAR detector at SLAC, we present preliminary measurements of the branching fractions for charmless hadronic decays of B mesons into two-body, quasi two-body and three-body nal states with pions, kaons, and  and a0 resonances. In the search for exclusive B0 ! +−0, we measure B(B0 ! (770) ) = (28:95:44:3)  10−6, together with the relative asymmetry Aphys = −0:04  0:18  0:02. We also set the upper limits on B0 ! 0(770)0, non-resonant B0 ! +−0, B0 ! a  0 (! ) and B0 ! K0 K0.
