The BABAR detector, which operates at the SLAC PEPII asymmetric e+e- collider at energies near the Y(4S) resonance has collected about 23M B-anti-B pairs in year 2000. Based on this data sample, we present the first study of sin(2b), with…
We search for decays of a B meson into a neutral D meson and a kaon, with the D meson decaying into K+pi-pi0. This final state can be reached through the b --> c transition B- -> D0K- followed by the doubly Cabibbo-suppressed D0 -->…
