We present a study of events with W bosons and hadronic jets produced in (p) over barp collisions at a center of mass energy of 1.8 TeV. The data consist of 51400 W-->e nu decay candidates from 108 pb(-1) of integrated luminosity collected using the CDF detector at the Fermilab Tevatron collider. Cross sections and jet production properties have been measured for W+greater than or equal to1 to greater than or equal to4 jet events. The data compare well to predictions of leading-order QCD matrix element calculations with added gluon radiation and simulated parton fragmentation.

Abstract
We present a study of events with W bosons and hadronic jets produced in (p) over barp collisions at a center of mass energy of 1.8 TeV. The data consist of 51400 W-->e nu decay candidates from 108 pb(-1) of integrated luminosity collected using the CDF detector at the Fermilab Tevatron collider. Cross sections and jet production properties have been measured for W+greater than or equal to1 to greater than or equal to4 jet events. The data compare well to predictions of leading-order QCD matrix element calculations with added gluon radiation and simulated parton fragmentation.
