Measurement of $\gamma$ from $B$ meson decay to $D^{(*)}K^{(*)}$

The LHCb experiment has measured the angle γ of the unitarity triangle using B → D (∗)K (∗) decays and with an integrated luminosity data sample of up to 4 fb−1 at energies in the centerof-mass of 7, 8 and 13 TeV. Many modes have been used, but the most recent results have been obtained with the GLW and ADS two-body decays and their extensions, the quasi-GLW and quasi-ADS modes. They are described in this paper and the results obtained by the LHCb collaboration are given. The γ angle measurement of LHCb is the combination of many modes among which the charged B decays contributed, and the most precise measurement from a single experiment.
