Book Description
We have observed exclusive [gamma][gamma] production in proton-antiproton collisions at the Tevatron at √ s = 1.96 TeV. We use data corresponding to 1.11 ± 0.07 fb-1 integrated luminosity taken by the Run II Collider Detector at Fermilab, with a trigger requiring two electromagnetic showers, each with transverse energy ET > 2 GeV, and vetoing on hits in the forward beam shower counters. We select events with two electromagnetic showers, each with transverse energy ET > 2.5 GeV and pseudorapidity.

Book Description
We present the first observation in hadronic collisions of the electroweak production of vector boson pairs (VV; V = W, Z) where one boson decays to a hadronic final state. The data correspond to 3.5 fb−1 of integrated luminosity collected by the CDF II detector in p{bar p} collisions at a center-of-mass energy of 1.96 TeV. Event selection requires two identified jets and large transverse momentum imbalance. The analysis employs several novel techniques to suppress multijet background and reduce systematic uncertainties. We observe 1516 ± 239(stat) ± 144(syst) diboson candidate events and measure a cross section of [sigma](p{bar p} 2!VV + X) = 18.0 ± 2.8(stat) ± 2.4(syst) ± 1.1(lumi) pb, in agreement with standard model (SM) expectations.

Book Description
These proceedings present the most up-to-date status of deep inelastic scattering (DIS) physics. Topics such as structure function measurements and phenomenology, quantum chromodynamics (QCD) studies in DIS and photoproduction, spin physics and diffractive interactions are reviewed in detail, with emphasis on those studies that push the test of QCD and the Standard Model to the limits of their present range of validity, towards both the very high and the very low four-momentum transfers in lepton-proton scattering.

Book Description
The authors present some precision measurements on electroweak physics performed at the Tevatron collider at Fermilab. Namely they report on the boson-pair production cross sections and on triple gauge boson couplings using proton anti-proton collisions collected by the CDF and D0 experiments at the center-of-mass energy of 1.96 TeV. The data correspond to an integrated luminosity of up to 324 pb{sup -1}.
