W, Z + jets at Tevatron

PDF Version Also Available for Download.

Description

We report the production jet cross-sections and properties in W and Z events using data from collisions with {radical}s = 1800 GeV at Fermilab Tevatron. Observed distributions in general agree with predictions of leading order QCD matrix element calculations with added gluon radiations and simulated parton fragmentations; however, some limitations of LO QCD predictions are also observed. The cross-section ratio of W + {>=} 1 jet events to inclusive W events is reported and compared with next-to-the-leading order QCD expectations. Good agreement between data and theory is seen. The color coherence effects are also observed in W+ jets events.
