Query: W + Jet Production at CDF   The cross section for the inclusive production of W bosons in association
with jets in ppbar collisions at sqrt(s)=1.96 TeV using the Collider Detector
at Fermilab (CDF II) is presented. The measurement is based on an integrated
luminosity of 320pb^-1, and includes events with up to 4 or more jets. In each
jet multiplicity sample the differential and cumulative cross sections with
respect to the transverse energy of the i^th-jet are measured. For W+>=2 jets
the differential cross section with respect to the 2-leading jets invariant
mass m_j1j2 and angular separation Delta R_j1j2 is also reported. The data are
compared to predictions from Monte Carlo simulations.
