Measurement of branching-fraction ratios and $CP$ asymmetries in $B^{\pm }\to D_{CP\pm }{K}^{\pm }$ decays at Belle and Belle II

The Belle, Belle II Collaborations, : +427

We report results from a study of $B^{\pm }\to D{K}^{\pm }$ decays followed by $D$ decaying to $CP$~eigenstates, where $D$ indicates a $D^0$ or ${\bar{D}}^0$ meson. These decays a…
