英文摘要	A binned dalitz plot analysis of the decays b (0) -> dk*(0), with d -> k (s) (0) pi(+)pi(-) and d -> k (s) (0) k+k-, is performed to measure the observables x(+/-) and y(+/-), which are related to the ckm angle gamma and the hadronic parameters of the decays. the d decay strong phase variation over the dalitz plot is taken from measurements performed at the cleo-c experiment, making the analysis independent of the d decay model. with a sample of proton-proton collision data, corresponding to an integrated luminosity of 3.0 fb(-1), collected by the lhcb experiment, the values of the cp violation parameters are found to be x(+) = 0.05 +/- 0.35 +/- 0.02, x(-) = -0.31 +/- 0.20 +/- 0.04, y(+) = -0.81 +/- 0.28 +/- 0.06 and y(-) = 0.31 +/- 0.21 +/- 0.05, where the first uncertainties are statistical and the second systematic. these observables correspond to values gamma = (71 +/- 20)degrees, gamma(b0) = 0.56 +/- 0.17 and delta(b0) = (204(-20)(+21))degrees. the parameters gamma(b0) and delta(b0) are the magnitude ratio and strong phase difference between the suppressed and favoured b-0 decay amplitudes, and have been measured in a region of +/- 50 mev/c(2) around the k*(892)(0) mass and with the magnitude of the cosine of the k*(892)(0) helicity angle larger than 0.4.
