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 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 K_S 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.
