Abstract

Measurements of CP observables in B± → DK∗± decays are presented, where D denotes a superposition of D0 and ¯ D0 meson states. Decays of the D meson to K−π+, K−K+, π−π+, K−π+π−π+ and π−π+π−π+ are used and the K∗± meson is reconstructed in the K0 Sπ± final state. This analysis uses a data sample of pp collisions collected with the LHCb experiment, corresponding to integrated luminosities of 1fb−1, 2fb−1 and 1.8fb−1 at centre-of-mass energies √s = 7TeV, 8TeV and 13TeV, respectively. The sensitivity of the results to the CKM angle γ is discussed.
