Study of $\overline{B}$$^{0}$ →D$^{+}$h$^{–}$ (h=K/π) decays at Belle

We present a measurement of the branching fractions of the Cabibbo favored $\overline{B}$$^{0}$ →D$^{+}$π$^{–}$ and the Cabibbo suppressed $\overline{B}$$^{0}$ →D$^{+}$K$^{–}$ decays. We find
B($\overline{B}$$^{0}$ →D$^{+}$π$^{–}$)=(2.48±0.01±0.09±0.04)×10$^{–3}$ and B($\overline{B}$$^{0}$ →D$^{+}$K$^{–}$)=(2.03±0.05±0.07±0.03)×10$^{–4}$ decays, where the first uncertainty is statistical, the second is systematic, and the third uncertainty is due to the D$^{+}$→K$^{–}$ π$^{+}$π$^{–}$ branching fraction. The ratio of branching fractions of $\overline{B}$$^{0}$ →D$^{+}$K$^{–}$ and $\overline{B}$$^{0}$ →D$^{+}$π$^{–}$ is measured to be R$^{D}$=[8.19±0.20(stat)±0.23(syst)]×10$^{–2}$. These measurements are performed using the full Belle dataset, which corresponds to 772×10$^{6}$ B$\overline{B}$ pairs and use the Belle II software framework for data analysis.
