Properties of Jets inWBoson Events from 1.8 TeVp¯pCollisions

We present a study of events with $W$ bosons and hadronic jets produced in $\overline{p}p$ collisions at a center of mass energy of 1.8 TeV. The data consist of 51 400 $W^{\pm }\to e^{\pm }\nu$ decay candidates from $108{\mathrm{pb}}^{-1\mathrm{}}$ of integrated luminosity collected using the CDF detector at the Fermilab Tevatron Collider. Cross sections and jet production properties have been measured for $W+\ge 1$ to $\ge 4$ jet events. The data are compared to predictions of leading-order QCD matrix element calculations with added gluon radiation and simulated parton fragmentation.
