Measurement of the branching fractions and $CP$ asymmetries of $B^{+}\to {\pi }^{+}{\pi }^0$ and $B^{+}\to K^{+}{\pi }^0$ decays in 2019-2021 Belle II data

Belle II Collaboration, F. Abudinén, I. Adachi +582

We determine the branching fractions $\mathcal{B}$ and $CP$ asymmetries ${\mathcal{A}}_{CP}$ of the decays $B^{+}\to {\pi }^{+}{\pi }^0$ and $B^{+}\to K^{+}{\pi }^0$. The result…
