Measurement of CP observables in B ± → DK *± decays using two- and four-body D final states

Abstract Measurements of CP observables in B ± → DK *± decays are presented, where D denotes a superposition of D 0 and D¯0 $$ {\overline{D}}^0 $$ 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 0 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 $$ \sqrt{s}=7 $$ TeV, 8 TeV and 13 TeV, respectively. The sensitivity of the results to the CKM angle γ is discussed.
