| description | ATLAS is a general-purpose experiment at the Large Hadron Collider. Beside other goals, it also aims at the study of B -hadrons. B -physics offers a large number of channels that can provide information about some fundamental properties of our universe. Among them, the B 0 d ! K 0 + - decay is sensitive to the potential presence of particles that are not predicted by the Standard Model. Such ”new physics” effects can be observed indirectly by studying angular distributions of the B 0 d ! K 0 + - decay products. This thesis describes the analysis of 4.9 fb - 1 of data produced in the proton-proton collisions at the centre-of-mass energy p s = 7 TeV at the LHC in the year 2011 and recorded by the ATLAS detector. The main steps of analysis are described, such as the selection of the signal events, the data fit procedure and the estimation of uncertainties. The obtained results are compared with other experiments and with the Standard Model prediction. |
