| contents | A recent combination of measurements performed by the LHCb collaboration determined that $γ=(63.8^{+3.5}_{-3.7})^\circ$. The fit combined the results of $γ$ and charm measurements, which resulted in precision improvements for the strong-phase difference between $D^0 \to K^-π^+$ and $D^0 \to K^+π^-$ decays, $δ_{Kπ}^{D}$, and the $D^0-\bar{D}^0$ mixing parameter, $y$. In addition, new LHCb measurements of the CKM angle $γ$ using $B^0 \to D K^{*0}$ and $B^- \to D^{*} K^-$ decays with the $D\to K_{S}^0 h^+ h^-$ final state (where $h=π,K$) are presented. |
