Abstract
A measurement of CP-violating observables in B± → D∗K± and B± → D∗π ± decays is made where the photon or neutral pion from the D∗ → Dγ or D∗ → Dπ0 decay is not reconstructed. The D meson is reconstructed in the self-conjugate decay modes, D → K0 Sπ +π − or D → K0 SK+K−. The distribution of signal yields in the D decay phase space is analysed in a model-independent way. The measurement uses a data sample collected in proton-proton collisions at centre-of-mass energies of 7, 8, and 13 TeV, corresponding to a total integrated luminosity of approximately 9 fb−1 . The B± → D∗K± and B± → D∗π ± CP-violating observables are interpreted in terms of hadronic parameters and the CKM angle γ, resulting in a measurement of γ = (92+21 −17) ◦ . The total uncertainty includes the statistical and systematic uncertainties, and the uncertainty due to external strong-phase inputs.
