Abstract

We present a study of differential two jet ratios in multi-hadronic final states produced by e+e− annihilation in the AMY detector at TRISTAN. The data are compared to the predictions of the next-to-leading logarithm parton-shower (NLL PS) Monte Carlo and the O(αs2) matrix element QCD models. We determine the strong coupling strength αs(57.3 GeV) = 0.130 ± 0.006.
