Study of (B)over-bar(0) -> D(+)h(-) (h = K/pi) decays at Belle
Original language description
We present a measurement of the branching fractions of the Cabibbo favored (B) over bar (0) -> D+pi(-) and the Cabibbo suppressed (B) over bar (0) -> D+K- decays. We find B((B) over bar (0) -> D+pi(-)) = (2.48 +/- 0.01 +/- 0.09 +/- 0.04) x 10(-3) and B((B) over bar (0) -> D+K-) = (2.03 +/- 0.05 +/- 0.07 +/- 0.03) x 10(-4) decays, where the first uncertainty is statistical, the second is systematic, and the third uncertainty is due to the D+ -> K-pi(+)pi(+) branching fraction. The ratio of branching fractions of (B) over bar (0) -> D+K- and (B) over bar (0) -> D+pi(-) is measured to be R-D = [8.19 +/- 0.20(stat) +/- 0.23(syst)] x 10(-2). These measurements are performed using the full Belle dataset, which corresponds to 772 x 10(6) B (B) over bar pairs and use the Belle II software framework for data analysis.
