Abstract

The measurements of electroweak sector of the Standard Model are presented, including most recent results from LEP, Tevatron and HERA colliders. The robustness of the Standard Model is illustrated with the precision measurements, the electroweak fits and the comparisons to the results obtained from low energy experiments. The status of the measurements of the $W$ boson properties and rare production processes involving weak bosons at colliders is examined, together with the measurements of the electroweak parameters in $ep$ collisions.
