Abstract

Measurements of CP observables in B± → D K*± decays are presented, where D denotes a superposition of D0 and anti-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 KS0 π± final state. This analysis uses a data sample of pp collisions collected with the LHCb experiment, corresponding to integrated luminosities of 1 fb^−1, 2 fb^−1 and 1.8 fb^−1 at centre-of-mass energies √s = 7 TeV, 8 TeV and 13 TeV, respectively. The sensitivity of the results to the CKM angle γ is discussed.
