We measure the strong coupling constant at NNLO corrections. We do this analysis with moments of event shape variables: thrust, C parameter, heavy jet mass, wide and total jet broadening, by fitting the L3 and DELPHI data ...

Abstract: We have analyzed the hadronization process in e^+ e^- annihilation. We use Monte Carlo data simulated by PYTHIA program. We have compared our results with AMY real data. Similar analysis techniques have been ...
