Abstract
We present a study of differential two jet ratios in multi-hadronic fi nal states produced by e(+)e(-) annihilation in the AMY detector at TR ISTAN. The data are compared to the predictions of the next-to-leading logarithm parton-shower (NLL PS) Monte Carlo and the O(alpha(s)(2)) m atrix element QCD models. We determine the strong coupling strength al pha(s)(57.3 GeV) = 0.130 +/- 0.006.
