Full TextAbstract
The hadronic events from the AMY data at 60 GeV center-of-mass energy are studied. We measure the coupling constant as first by using the three-jet rate method. From the event shape, we also extract the strong coupling constant, based on next-to-next leading order. Our results are consistent with the running of as expected from quantum chromodynamics predictions at next-to-next leading order corrections.
