Electroweak Precision Tests ∗

The Standard Model (SM) constitutes one of the most successful achievements in modern physics. It provides a very elegant theoretical framework, which is able to describe all known experimental facts in particle physics. A detailed description of the SM and its impressive phenomenological success can be found in Refs. [1] and [2], which discuss the electroweak and strong sectors, respectively. ...

Precision Tests of Quantum Chromodynamicsand

We discuss three topics relevant to testing the Standard Model to high precision: commensurate scale relations, which relate observables to each other in pertuba-tion theory without renormalization scale or scheme ambiguity, the relationship of compositeness to anomalous moments, and new methods for measuring the anomalous magnetic and quadrupole moments of the W and Z. 1. Introduction One of t...

Precision Tests of the Mssm. *

We present the results of a global fit to the electroweak observables in the MSSM in which, for the first time, all the (relevant) low energy parameters of the model are treated as independent variables. The best fit selects either very low or very large values of tanβ and chargino (higgsino–like) and stop or/and the CP−odd Higgs boson are within the reach of LEP 2. Moreover, the best fit gives...

Electroweak Precision Tests at GigaZ

By running the prospective high-energy ee collider TESLA in the GigaZ mode on the Z resonance, experiments can be performed on the basis of more than 10 Z events. This will allow the measurement of the effective electroweak mixing angle to an accuracy of δ sin θeff ≈ ±1×10. The W boson mass is likewise expected to be measurable with an error of δMW ≈ ±6 MeV near the WW threshold. We review the ...

Precision Tests of Electroweak Physics

We review the current status of precision electroweak measurements and the constraints they impose on new physics. We perform a model independent analysis using the ST U –formalism of Ref. 1, and then discuss how the Z–pole data from LEP and SLD can be used to constrain models that are not covered within that framework. We review the current status of precision electroweak measurements and the ...
