A study of QCD structure constants and a measurement of at LEP using event shape observables
Abstract
The dependence of event shape cross sections on the QCD structure constantsCA,CF andTF is studied using data from the OPAL detector at LEP. The observables Thrust, Heavy Jet Mass, Total and Wide Jet Broadening are used. They allow the use ofO(αs2), resummed NLLA, and combinedO(αs2) plus resummed NLLA QCD calculations so that a comparison between the different approaches can be performed. The measured values of the structure constants are found …
