Abstract

Measurements of CP observables and the CKM angle γ are performed in B± → D K*(892)± decays, where D represents a superposition of D0 and anti-D0 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 K0S π+ π− and K0S K+ K−. This analysis includes the first observation of the suppressed B± → [π± K∓]_D K*± and B± → [π± K∓ π± π∓]_D K*± decays. The combined result gives γ=(63±13)º.
