Description
The status of the work towards a measurement of the CKM angle $\gamma$ with $B_d^0 → D^{∓} π^{±}$ decays in the LHCb run 2 data set is presented. The work presented includes signal isolation, time resolution studies, and neutral $B$ meson flavour tagging. Neutral $B$ meson flavour tagging is an integral component of analyses of this kind, which allows for the separation of $B_d^0$ and $\overline{B}_d^0$ events. This analysis includes first results for use of the new, neural network based, inclusive flavour tagger in parallel with conventional tagging techniques. Measurement of the CKM angle $\gamma$ is an important avenue for testing the standard model and each new measurement helps us to reach an ever greater level of precision. This measurement will improve the LHCb $\gamma$ combination, which is currently the world's most precise direct measurement and contains contributions from over 30 measurements.
