### Description

Charged $B$ decays of the form $B^\pm \rightarrow DK^\pm$ (where $D$ represents either a $D^0$ or a $\bar{D^0}$) are powerful tools in the measurement of the $CP$-violating CKM angle $\gamma$. Channels where the $D$ decays to a final state involving a $\pi^0$, such as $D \rightarrow \pi^\pm K^\mp \pi^0$, $D \rightarrow \pi^\pm \pi^\mp \pi^0$ and $D \rightarrow K^\pm K^\mp \pi^0$ are promising modes for these studies, but present challenges in the fierce environment of the LHC. In this talk I shall demonstrate that the excellent performance of the LHCb detector allows for high purity samples of these decay modes to be isolated, and consequently, their use in an ongoing $CP$-violation analysis using 3.0 fb$^{-1}$ of data.
