Tests of the Electroweak Sector of the Standard Model

The Electroweak sector of the Standard Model is reviewed and best fits are presented for its free parameters based on currently available experimental tests. The Standard Model remains an excellent descriptions of the available experimental data. The preferred mass range of the still elusive Higgs boson in the Standard Model is $114<m_{\mathrm{H}}<219$ GeV at the 95% Confidence Level. A Standard Model Higgs in this mass range is likely to be observed in the years 2007--2010, either at the Tevatron or at the LHC.
