Measurement of strong coupling constant by using event shape moments in perturbative theory

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 with NNLO model. Our real data are consistent with NNLO calculations, because...

Zusammenfassung:	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 with NNLO model. Our real data are consistent with NNLO calculations, because it involves higher order terms in QCD calculations.
