DOWNLOAD EBOOKWe present a study of events with Z bosons and jets produced at the Fermilab Tevatron Collider in p{bar p} collisions at a center of mass energy of 1.96 TeV. The data sample consists of nearly 14,000 Z/[gamma]* 2!ee− candidates corresponding to the integrated luminosity of 340 pb−1 collected using the D0 detector. Ratios of the Z/[gamma]* + d"n jet cross sections to the total inclusive Z/[gamma]* cross section have been measured for n = 1 to 4 jet events. Our measurements are 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.
