Search for CP violation in charged D meson decays
At the present time, Charge-Parity asymmetry or CP Violation is one of the most studied topics in high energy physics. Precise measurements of CP parameters can test sensitive sectors of the Standard Model (SM). These measurements could also give us clues about physics beyond the SM. Furthermore, since CP Violation is one of the necessary conditions for generating a matter-antimatter asymmetric Universe according to the baryogenesis model of Sakharov, a better understanding of these processes will improve our knowledge about the origin of the Universe. CP Violation in single Cabibbo-Suppressed charged D meson decays is predicted by the SM to have asymmetries of the order of {Omicron}(10{sup -3}), results bigger than this will be strong evidence of physics beyond the SM. We report results of the search for CP violation in D{sup +} {yields} K{sup -}K{sup +}{pi}{sup +} meson decays. The selection criteria were optimized using a control sample from data with a luminosity of 9.8 fb{sup -1}.
