dc.description.abstract | Branching fraction and asymmetry measurements of charmless B + → K * + h + 1 h − 2 (where h 1 , 2 = K , π ) decays are presented, using a data sample of 232 × 10 6 Υ ( 4 S ) → B ¯¯¯ B decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. Using a maximum likelihood fit, the following branching fraction results were obtained: B ( B + → K * + K + K − ) = ( 36.2 ± 3.3 ± 3.6 ) × 10 − 6 and B ( B + → K * + π + π − ) = ( 75.3 ± 6.0 ± 8.1 ) × 10 − 6 . Upper limits were set for B ( B + → K * + π + K − ) < 11.8 × 10 − 6 and B ( B + → K * + K + π − ) < 6.1 × 10 − 6 at 90% confidence level. The charge asymmetries for the decays B + → K * + K + K − and B + → K * + π + π − were measured to be A K ∗ K K = 0.11 ± 0.08 ± 0.03 and A K ∗ π π = 0.07 ± 0.07 ± 0.04 , respectively. The first error quoted on branching fraction and asymmetry measurements is statistical and the second systematic. | - |
