英文摘要Measurements of cp observables in b-+/- -> d(*)k-+/- and b-+/- -> d(*)pi(+/-) decays are presented, where d(*) indicates a neutral dor d* meson that is an admixture of d(*)(0) and (d) over bar(*)(0) states. decays of the d* meson to the d pi(0)and d gamma final states are partially reconstructed without inclusion of the neutral pion or photon, resulting in distinctive shapes in the bcandidate invariant mass distribution. decays of the d meson are fully reconstructed in the k-+/-pi(-/+), k+k- and pi(+)pi(-) final states. the analysis uses a sample of charged bmesons produced in ppcollisions collected by the lhcb experiment, corresponding to an integrated luminosity of 2.0, 1.0 and 2.0fb- 1taken at centre- of- mass energies of root s = 7, 8 and 13 tev, respectively. the study of b-perpendicular to -> d*k-perpendicular to and b-perpendicular to -> d*pi(perpendicular to) decays using a partial reconstruction method is the first of its kind, while the measurement of b-+/- -> dk +/- and b-+/- -> d pi(+/-) decays is an update of previous lhcb measurements. the b-+/- -> dk +/- results are the most precise to date.
