| Popis: |
We present a measurement of the branching fractions of the Cabibbo favored ̄B0 → Dþπ− and theCabibbo suppressed ̄B0 → DþK− decays. We find Bð ̄B0 → Dþπ−Þ ¼ ð2.48 0.01 0.09 0.04Þ ×10−3 and Bð ̄B0 → DþK−Þ ¼ ð2.03 0.05 0.07 0.03Þ × 10−4 decays, where the first uncertainty isstatistical, the second is systematic, and the third uncertainty is due to the Dþ → K−πþπþ branchingfraction. The ratio of branching fractions of ̄B0 → DþK− and ̄B0 → Dþπ− is measured to beR D ¼ ½8.19 0.20ðstatÞ 0.23ðsystÞ × 10−2. These measurements are performed using the full Belledataset, which corresponds to 772 × 10 6B ̄B pairs and use the Belle II software framework for data analysis. |
