Abstract

With use of the MARK-J detector at s=34.7 GeV 21 000 e+e-→hadron events have been collected. By measurement of the asymmetry in angular energy correlations the strong coupling constant αs=0.13±0.01(statistical) ±0.02(systematic) is determined, in complete second order, and independent of the fragmentation models and QCD cutoff values used.
