English AbstractA model-dependent amplitude analysis of the decay b (0) -> d(k (s) (0) pi (+) pi (-))k (au 0) is performed using proton-proton collision data corresponding to an integrated luminosity of 3.0 fb(-1), recorded at and 8 tev by the lhcb experiment. the cp violation observables x (+/-) and y (+/-), sensitive to the ckm angle gamma, are measured to be x- = 0.15 +/- 0.14 +/- 0.03 +/- 0.01; y- = 0.25 +/- 0.15 +/- 0.06 +/- 0.01; x+ = 0.05 +/- 0.24 +/- 0.04 +/- 0.01; y+ = 0.65(-0.23)(+0.24) +/- 0.08 +/- 0.01; where the first uncertainties are statistical, the second systematic and the third arise from the uncertainty on the d -> k (s) (0) pi (+) pi (-) amplitude model. these are the most precise measurements of these observables. they correspond to gamma = (80 (- 22) (+ 21) )a degrees and , where is the magnitude of the ratio of the suppressed and favoured b (0) -> dk (+) pi (-) decay amplitudes, in a k pi mass region of +/- 50 mev around the k (*)(892)(0) mass and for an absolute value of the cosine of the k (*0) decay angle larger than 0.4.
