Book Description
The search for WW and WZ production in p[anti p] collisions at[radical]s= 1.8 TeV using the CDF and D0 detectors is presented. Three analyses, one concentrating on the leptons+ jets decay channels and two concentrating on the dilepton decay channels are described in detail. Limits on anomalous WW[gamma] and WWZ trilinear gauge boson couplings are presented. Prospects for further study of diboson production and anomalous couplings with the Upgraded Tevatron are also presented.
Evidence of WW+WZ Production with Lepton + Jets Final States in P Anti-p Collisions at S**1/2

Book Description
We present the first evidence of WW+WZ production with lepton+jets final states at a hadron collider. The data correspond to 1.07 inverse femtobarns of integrated luminosity collected with the D0 detector at the Fermilab Tevatron Collider in proton-antiproton collisions at sqrt(s)=1.96 TeV. The observed cross section for WW+WZ production is 20.2 +/- 4.5 pb, consistent with the SM prediction of 16.1 +/- 0.9 pb. The probability for background fluctuations to produce an excess equal to or larger than that observed is estimated to be 5.4e-6, corresponding to a significance of 4.4 standard deviations.

Book Description
We present a preliminary result from a search for anomalous WW and WZ production in p[bar p] collisions at[radical]s= 1.8 TeV using p[bar p][yields] e[nu]jj events observed during the 1992-1993 run of the Fermilab Tevatron collider. A fit to the p[sub T] spectrum of W(e[nu]) yields direct limits on the CP-conserving anomalous WW[gamma] and WWZ coupling parameters of -0.89
Z Boson Transverse Momentum Distribution, and ZZ and WZ Production

Book Description
This work develops novel data analysis techniques enabling aspects of the Standard Model of particle physics to be tested with unprecedented precision using data from the DZero experiment at the high energy “Tevatron” proton-antiproton collider at Fermilab, Chicago. Vesterinen's measurements of the transverse momentum of Z bosons using the novel variable φ* have exposed deficiencies in the current state-of-the-art theoretical predictions for vector boson production at hadron colliders. These techniques are now being used in the experiments at CERN’s Large Hadron Collider (LHC) and have stimulated considerable interest in the theoretical particle physics community. Furthermore, Vesterinen's measurements of the cross sections for the production of pairs of vector bosons (WZ and ZZ) are to date the most precise ever made.
Diboson Production at the Tevatron

Book Description
We present the latest results on the production of WW, WZ, Wgamma, Zgamma and ZZ events at the Fermilab Tevatron Collider. The results are based on the analyses of 0.2 - 2 /fb of data collected in p pbar collisions at sqrt(s) = 1.96 TeV by CDF and DO experiments during the Tevatron Run II. Analyses of the diboson production processes provide crucial test of the Standard Model, directly probing its predictions on the Trilinear Gauge Couplings.

Book Description
The standard model of particle physics is expected to be a low energy effective theory valid for particle interactions below the TeV scale. Above this scale, extensions to the standard model (SM) augment the existing particle content, leading to enhanced production of many final states at colliders. Specifically, the production and decay of massive charged or neutral particles can produce an excess of W boson pairs for neutral particles or W and Z boson pairs for charged particles. We search for resonant WW or WZ production using up to 5.4 fb−1 of integrated luminosity collected by the D0 experiment in Run II of the Fermilab Tevatron Collider. The data are consistent with the standard model background expectation, and we set limits on a resonance mass using the sequential standard model (SSM) W(prime) boson and the Randall-Sundrum model graviton G as benchmarks. We exclude an SSM W(prime) boson in the mass range 180-690 GeV and a Randall-Sundrum graviton in the range 300-754 GeV at 95% CL.
