Precision electroweak tests of the Standard Model Electroweak Physics at LHCb Precision electroweak physics at LEP Weakly coupled Higgsless theories and precision electroweak tests Very light sbottom and gluino scenario confronting electroweak precision tests. The Large Electron–Positron Collider (LEP) was one of the largest particle accelerators ever constructed.. It was built at CERN, a multi-national centre for research in nuclear and particle physics near Geneva, collided electrons with positrons at energies that reached GeV. It was a circular collider with a circumference of 27 kilometres built in a tunnel roughly m.   Electroweak precision tests of the Standard Model of the fundamental interactions are reviewed ranging from the lowest to the highest energy experiments. Results from global fits. Figure 1: Global fit to all published data sensitive to the Higgs boson mass. This comprises direct searches as well as electroweak precision data. The left vertical axis shows goodness-of-fit relative to the minimum χ 2 value, while the right vertical axis shows σ values as a function of Higgs mass. The dashed line shows the situation before the Tevatron publications, while they are.

We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and thousand Z decays by the SLD experiment using a polarised beam. results presented in are new preliminary combinations of final LEP-II results on the mass and width of the W boson. Including the precision electroweak measurements performed at the Z pole published recently, the results are compared with precise electroweak measurements from other experiments, notably CDF and DØ at the Tevatron.

Experimental measurements of electroweak observables are described with reference to studies performed at the e+e- collider LEP at energies close to the Z0 peak. The theoretical predictions are compared with experimental data and their implications for the Standard Model are discussed.

We show that the Unhiggs is consistent with electroweak precision tests when its mass gap is at the weak scale; in fact, it then mimics a light SM Higgs boson. We also argue that the Unhiggs, while being perfectly visible to electroweak precision observables, is invisible to detection at LEP.

The presented data has been taken at the LEP Collider at CERN at center-of-mass energies up to GeV. Updates on the LEP I Z 0 lineshape and asymmetry measurements will be presented and the current status of the precision W-Boson mass measurement at LEP II will be discussed.

The significance of the program of precision tests of the electroweak theory at LEP cannot be disputed. In a relative sense, this program can be seen as the main goal of LEP in the years'92, '93, up to the completion of the first LEP phase (LEP I) before the energy upgrade (LEP II).

It is very hard to remember how little we knew before LEP and the giant step that LEP made. It was often said that LEP discovered electroweak radiative corrections at the level of 5 σ, opening up a precision era in particle physics that continues to set the standard today and offer guidance on the elusive new physics beyond the SM.

The LEP programme offers unique possibilities for electroweak precision tests. Through the copious production of Z° bosons in the clean environment of the e+e~ collider, a wealth of physical observables sensitive to the electroweak couplings are accessible.

A promising avenue to perform precision tests of the SM at the LHC is to measure differential cross-sections at high invariant mass, exploiting in this way the growth with the energy of the corrections induced by heavy new physics. We classify the leading growing-with-energy effects in longitudinal diboson and in associated Higgs production processes, showing that they can be.

The final chapters give an outlook on the electroweak physics at a future linear : $ One approach is a generalization of the electroweak theory, called supersymmetry, that associates new particles with all the known quarks and leptons and force particles. Over the last several years the Standard Model (SM) of electroweak interactions has been subjected to precision tests through a variety measurements at LEP, SLC and Tevatron.

While the measurements at Z pole are sensitive to the presence of top quark and Higgs boson via weak radiative corrections, the direct measurement of top quark mass at Teva.Emphasis is put on the properties of the electroweak gauge bosons, which was the main research field at LEP.
