dc.description.abstract | Branching fraction measurements of charmless B 0 → K * 0 h + 1 h − 2 ( h 1 , 2 = K , π ) decays are presented, using a data sample of 383 × 10 6 Υ ( 4 S ) → B ¯¯¯ B decays collected with the BABAR detector at the PEP-II asymmetric-energy B -meson factory at SLAC. The results are B ( B 0 → K * 0 K + K − ) = ( 27.5 ± 1.3 ± 2.2 ) × 10 − 6 , B ( B 0 → K * 0 π + K − ) = ( 4.6 ± 1.1 ± 0.8 ) × 10 − 6 , and B ( B 0 → K * 0 π + π − ) = ( 54.5 ± 2.9 ± 4.3 ) × 10 − 6 . The first errors quoted are statistical and the second are systematic. An upper limit is set for B ( B 0 → K * 0 K + π − ) < 2.2 × 10 − 6 at 90% confidence level. We also present measurements of C P -violating asymmetries for the observed decays. | - |
