Popis: We present a study of events with Z bosons and associated jets produced at the Fermilab Tevatron collider in p over(p, ̄) collisions at a center of mass energy of 1.96 TeV. The data sample consists of nearly 14 000 Z / γ* → e+ e- candidates corresponding to an integrated luminosity of 0.4 fb-1 collected with the DØ detector. Ratios of the Z / γ* + ≥ n jet cross sections to the total inclusive Z / γ* cross section have been measured for n = 1 - 4 jets, and found to be in good agreement with a next-to-leading order QCD calculation and with a tree-level QCD prediction with parton shower simulation and hadronization.
