Abstract: | Using 226 × 10 6 Υ ( 4 S ) → B ¯¯¯ B events collected with the BABAR detector at the PEP-II e + e − storage ring at the Stanford Linear Accelerator Center, we measure the branching fraction for B 0 → ¯¯¯ D 0 K + π − , excluding B 0 → D * − K + , to be B ( B 0 → ¯¯¯ D 0 K + π − ) = ( 88 ± 15 ± 9 ) × 10 − 6 . We observe B 0 → ¯¯¯ D 0 K ∗ ( 892 ) 0 and B 0 → D ∗ 2 ( 2460 ) − K + contributions. The ratio of branching fractions B ( B 0 → D * − K + ) / B ( B 0 → D * − π + ) = ( 7.76 ± 0.34 ± 0.29 ) % is measured separately. The branching fraction for the suppressed mode B 0 → D 0 K + π − is B ( B 0 → D 0 K + π − ) < 19 × 10 − 6 at the 90% confidence level. |
