## Abstract

Measurements of CP observables in B± → DK decays are presented, where D denotes a superposition of D0 and D¯ 0 meson states. Decays of the D meson to Kπ+, KK+, ππ+, Kπ+ππ+ and ππ+ππ+ are used and the K meson is reconstructed in the KS 0π± 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.
