 Abstract: Measurements of CP observables and the CKM angle γ are performed in B± → DK(892)± decays, where D represents a superposition of D0 and D0 states, us- ing the LHCb dataset collected during Run 1 (2011–2012) and Run 2 (2015–2018). A study of this channel is presented with the D meson reconstructed in two-body final states K±π, K+K and π+π; four-body final states K±ππ±π and π+ππ+π; and three- body final states KS0π+π and KS0K+K. This analysis includes the first observation of the suppressed B± → [π±K]DK∗± and B± → [π±Kπ±π]DK∗± decays. The combined result gives γ = (63 ± 13).
