Resum
A model-dependent amplitude analysis of B± → DK± with D → K0 S π +π − 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 γ, are measured to be x− = +0.027 ± 0.044 +0.010 −0.008 ± 0.001, y− = +0.013 ± 0.048 +0.009 −0.007 ± 0.003, x+ = −0.084 ± 0.045 ± 0.009 ± 0.005, y+ = −0.032 ± 0.048 +0.010 −0.009 ± 0.008, where the first uncertainty is statistical, the second systematic and the third arises from the uncertainty of the D → K0 S π +π − amplitude model. The value of γ is determined to be (84+49 −42) ◦ , including all sources of uncertainty. Neutral D meson mixing is found to have negligible effect.
