Precision Tests of the Standard Model

TL;DR

This paper reviews recent precision electroweak measurements, compares them with Standard Model predictions, and discusses how these results constrain fundamental parameters like the Higgs boson mass.

Contribution

It provides an updated synthesis of experimental data and their implications for the Standard Model, including new top quark and W boson measurements.

Findings

Measurements agree with Standard Model predictions

Constraints on Higgs boson mass are derived

Updated top quark and W boson data are presented

Abstract

Recent published and preliminary precision electroweak measurements are reviewed, including new results on the mass of the top quark and mass and width of the W boson. The experimental results are compared with the predictions of the Standard Model and are used to constrain its free parameters, notably the mass of the Higgs boson. The agreement between measurements and expectations from theory is discussed. (Invited talk presented at the EPS HEPP conference, Lisboa, Portugal, July 21st to 27th, 2005)
