| description | <p>Two measurements of the Cabibbo-Kobayashi-Maskawa angle γ using <em>B</em> → <em>DK</em> and <em>B</em><sup>0</sup> → <em>DK</em><sup>&ast;0</sup> decays are presented in this thesis. The subsequent <em>D</em> meson decays to the <em>K</em><sub>S</sub><sup>0</sup>π<sup>+</sup>π<sup>−</sup> and <em>K</em><sub>S</sub><sup>0</sup><em>K</em><sup>+</sup><em>K</em><sup>−</sup> final states are studied using a binned Dalitz plot analysis. The <em>D</em> strong-phase variation over the Dalitz plot is taken from measurements performed at the CLEO-c experiment, making the analysis independent of a model to describe the <em>D</em> decay amplitude. Both measurements are performed using proton-proton collision data collected by the Large Hadron Collider beauty (LHCb) experiment in 2011 and 2012, corresponding to an integrated luminosity of 3 fb<sup>−1</sup> at centre-of-mass energies √s = 7 TeV and 8 TeV. The value γ= (62 <sup>+15</sup><sub style="position: relative; left: -1.7em;">−14</sub>)° is measured using <em>B</em><sup>0</sup> → <em>DK</em><sup>&ast;0</sup> decays and γ = (71 ± 20)° is measured using <em>B</em><sup>0</sup> → <em>DK</em><sup>&ast;0</sup> decays, with a second solution for each value corresponding to γ + 180°. The measurements are consistent with the world average value of γ.</p> |
