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 D¯0 states, using 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±π∓π±π∓ and π+π−π+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±K∓π±π∓]DK*± decays. The combined result gives γ = (63 ± 13)°.
