Abstract: (SISSA)
The CKM angle γ\gamma is the least well-known angle of the Unitarity Triangle, and the only one easily accessible at tree level. Important constraints on \g are obtained from the analysis of B±D0K±B^{\pm} \to D^{0} K^{\pm} decays, where the D0D^{0} meson is reconstructed in the K+KK^+ K^- or π+π\pi^+ \pi^- final states; the latest world-best results using the Run 1 (2011 and 2012) and Run 2 (2015 and 2016) LHCb datasets are presented here. The measurement of B±D0K±B^{\pm} \to D^{*0} K^{\pm} decays using a partial reconstruction method is also performed at LHCb for the first time, where both D0D0π0D^{*0} \to D^{0} \pi^{0} and D0D0γD^{*0} \to D^{0} \gamma decays are considered. Both sets of results contribute to the ultimate goal of degree level precision on γ\gamma, via the exploitation of all possible channels and techniques.
