Review of Physics Results from the Tevatron

We present a comprehensive review of the physics results obtained by the CDF and D0 collaborations up to summer 2014, with emphasis on those achieved in the Run II of the Tevatron collider which delivered a total integrated luminosity of ~10 fb-1 at sqrt{s}=1.96 TeV. The results are presented in six main physics topics: QCD, Heavy Flavor, Electroweak, Top quark, Higgs boson and searches for New Particles and Interactions. The characteristics of the accelerator, detectors, and the techniques used to achieve these results are also briefly summarized.

Review of Physics Results from the Tevatron: Electroweak Physics

We summarize an extensive Tevatron (1984-2011) electroweak physics program that involves a variety of W and Z boson precision measurements. The relevance of these studies using single and associated gauge boson production to our understanding of the electroweak sector, quantum chromodynamics and searches for new physics is emphasized. We discuss the importance of the W boson mass measurement, the W/Z boson distributions and asymmetries, and diboson studies. We highlight the recent Tevatron measurements and prospects for the final Tevatron measurements.

Measurements of the Trilinear Gauge Boson Couplings from Diboson Production at D0

The most recent measurements of the trilinear gauge boson couplings from the diboson production at the D0 experiment has been presented. The analyzed final states are Zgamma->vvgamma, and WW->lvlv, and WW+WZ->lvjj. We also present results obtained combining all final states involving the W boson. These results represent the most strigent limits set to date at the hadron collider.

Diboson Production Cross Sections at $\sqrt{s}=1.96$ TeV

The increasing size of the data recorded by the CDF and DØ experiments at the Tevatron collider at $\sqrt{s}=$ 1.96 TeV makes the diboson physics program more accessible for probes of the electroweak gauge structure in the Standard Model. Here we summarize the most recent measurements of the diboson cross sections and limits on the trilinear gauge boson couplings.

Studies of Gauge Boson Production with a gamma/gamma-collider at TESLA

In absence of the Standard Model Higgs boson the interaction among the gauge bosons becomes strong at high energies and influences the couplings between them. Each trilinear and quartic gauge boson vertex is characterised by a set of couplings which are expected to deviate from their Standard Model values already at energies lower than the energy scale of the New Physics.The precise measurement of gauge boson couplings can provide clues to the mechanism of the electroweak symmetry breaking and their anomalous values can be a sign of a New Physics effect beyond the Standard Model. The estimated precisions of the trilinear gauge boson coupling (TGC) measurements at a photon collider are about one to two orders of magnitude higher than at LEP and Tevatron providing a measurement highly sensitive to the physics beyond the Standard Model. The optimisation of the forward region of the photon collider detector brings the amount of the low-energy background to the manageable level providing a clean environment for the TGC measurements at a photon collider with estimated precisions.

Trilinear Gauge Couplings from gamma/gamma to WW

If there is no the Standard Model Higgs boson, the interaction among the gauge bosons becomes strong at high energies (~ 1TeV). The effects of strong electroweak symmetry breaking could manifest themselves indirectly through the vertices as anomalous gauge boson couplings before they give rise to new physical states like resonances. Here a study of the measurement of trilinear gauge couplings kappa_gamma and lambda_gamma is presented looking at the hadronic decay channel of the WW boson pair at an gamma/gamma-collider. A sensitivity of order of 0.001-0.0001 can be reached depending on the coupling under consideration and on the initial polarisation state.
