Abstract

A model-dependent amplitude analysis of B-+/- -> DK +/- with D -> K-s(0)pi(+)pi(-) decays is performed using proton proton collision data, corresponding to an integrated luminosity of 1 fb(-1), recorded by LHCb at a centre-of-mass energy of 7 TeV in 2011. Values of the CP violation observables x +/- and y +/-, which are sensitive to the CKM angle gamma, are measured to be

x- = +0.027 +/- 0.0441(-0.008)(+0.010) +/- 0.001,

y- = +0.013 +/- 0.0481(-0.007)(+0.009) +/- 0.003,

x+ = -0.084 +/- 0.045 +/- 0.009 +/- 0.005,

y+ = -0.032 +/- 0.048(-0.009)(+0.010) +/- 0.008,

where the first uncertainty is statistical, the second systematic and the third arises from the uncertainty of the D -> K-S(0)pi(+)pi(-) amplitude model. The value of gamma is determined to be (84(-42)(+49))degrees including all sources of uncertainty. Neutral D meson mixing is found to have negligible effect. (C) 2014 The Authors.
