Abstract
Events with a (2+1) jet topology in deep-inelastic scattering at HERA are studied in the kinematic range 200 < Q(2) < 10000 GeV2. The rate o f (2+1) jet events has been determined with the modified JADE jet algo rithm as a function of the jet resolution parameter and is compared wi th the predictions of Monte Carlo models. In addition, the event rate is corrected for both hadronization and detector effects and is compar ed with next-to-leading order QCD calculations. A value of the strong coupling constant of alpha(s)(M-Z(2)) = 0.118 +/- 0.002 (stat.) (+0.00 7)(-0.008) (syst.) (+0.007)(-0.006) (theory) is extracted. the systema tic error includes uncertainties in the calorimeter energy calibration , in the description of the data by current Monte Carlo models, and in the knowledge of the parton densities. The theoretical error is domin ated by the renormalization scale ambiguity.
