Popis: The Sterman-Weinberg 2-jet cross section is measured from the hadron energy flow using the thrust axis to define the axis of the jet cone. The results are compared with first order QCD predictions. Deviations due to fragmentation are observed which decrease with increasing center of mass energy. We obtain an upper limit of Λmax≈523 MeV for the QCD scale parameter using a method which is insensitive to the details of the fragmentation. Moments of energy flow are also studied.
