W production and properties at CDF

W + Jet Production at Cdf

The cross section for the inclusive production of W bosons in association with jets in pp̄ collisions at √ s = 1.96 TeV using the Collider Detector at Fermilab (CDF II) is presented. The measurement is based on an integrated luminosity of 320 pb, 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 trans...

Observation of Diffractive W - Boson Production at the Tevatron CDF

We report the first observation of diffractively produced W bosons. In a sample of W → eν events produced in p¯ p collisions at √ s=1.8 TeV, we find an excess of events with a forward rapidity gap, which is attributed to diffraction. The probability that this excess is consistent with non-diffractive production is 1.1 × 10 −4 (3.8σ). The relatively low fraction of W + Jet events observed within...

Diiractive Dijet and W Production in Cdf

Results on diiractive dijet and W-boson production from CDF are reviewed and compared with predictions based on factorization of the diiractive structure function of the proton measured in deep inelastic scattering at HERA.

Quarkonia Production at CDF

Inclusive Jet Production at CDF

We present results on inclusive jet production in proton-antiproton collisions at √ s = 1.96 TeV. The measurements are based on 1.0 fb−1 of CDF Run II data and were carried out for jets in five different jet rapidity regions up to | Y |=2.1. Both the midpoint cone based algorithm and kT algorithm were investigated to reconstruct the jets. The results are compared to next-to-leading order pertur...
