Study of $Bto D^{(*)}h$ decays using $62.8~mathrm{fb}^{-1}$ of Belle II data

We report measurements related to hadronic $B$ decays to final states that contain charm mesons. The analyses are performed on a $62.8~mathrm{fb}^{-1}$ data set collected by the Belle II experiment at a center-of-mass energy corresponding to the mass of the $Upsilon(4S)$ resonance. The measurements reported are for the decay modes $B^-to D^0 h^-$, $B^{-}to D^{*0}h^-$, $bar{B}^{0}to D^{+} h^{-}$ and $bar{B}^{0}to D^{*+} h^{-}$, where $h=pi$ or $K$. These modes are either signal or control channels for measurements related to the unitarity triangle angle $gamma$ in direct or time-dependent $CP$-violation measurements. The reported observables are the ratios between the $Bto D^{(*)}K$ and $Bto D^{(*)}pi$ decay rates, which are found to be in agreement with previous measurements.
