摘要：

The strong coupling constant alpha(s) was determined from analyses of the thrust, heavy jet mass and, differential 2-jet rate, using e+e- hadronic events at square-root s = 58 GeV with the TOPAZ detector at TRISTAN. The NLLjet Monte Carlo simulation (NLLjet) and analytic formulae based on resummation up to the next-to-leading logarithms combined with O(alpha(s)2) calculations were used to evaluate alpha(s). The averaged alpha(s) values at Q2 = (58 GeV)2 from the analyses are alpha(s) = 0.125 +/- 0.009 for NLLjet and alpha(s) = 0.132 +/- 0.008 for the resummed analytic formulae.
