Determination of αs from a differential jet multiplicity distribution at SLC and PEP
Description
We measure the differential jet multiplicity distribution in e+e- annihilation with the Mark 2 detector. This distribution is compared with the second order QCD prediction and αs is determined to be 0.123 ± 0.009 ± 0.005 at √s ∼ MZ (at SLC) and 0.149 ± 0.002 ± 0.007 at √s = 29 GeV (at PEP). The running of αs between these two center of mass energies is consistent with the QCD prediction. The Q2 dependence of the ΛMS determination is also discussed. 21 refs., 3 figs
