Abstract

Measurements of CP observables in B-+/- -> DK*(+/-) decays are presented where D denotes a superposition of D-0, (D) over bar (0) meson states. Decays of the D meson to K-pi(+) K-K+ pi(-)pi(+), K-pi(+)pi(-)pi(+), pi(-)pi(+)pi(-)pi(+) are used, the K*(+/-) meson is reconstructed in the K-S(0)pi(+/-) 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), 1.8 fb(-1) at centre-of-mass energies root s = 7TeV 8TeV, 13TeV, respectively. The sensitivity of the results to the CKM angle gamma is discussed.
