Title: Electroweak measurements from hadron machines

Abstract

The discovery of the W and Z gauge bosons at the Sp{bar p}S in 1983 marked the beginning of direct electroweak measurements at a hadron machine. These measurements vindicated the tree level predictions of the Standard Model. The new generation of hadron collider machines now have data of such precision that the electroweak measurements are probing the quantum corrections to the Standard Model. The importance of these quantum corrections was recognized in the award of the 1999 Nobel Price. These corrections are being tested by a wide variety of measurements ranging from atomic parity violation in cesium to precision measurements at the Z pole and above in e{sup +}e{sup {minus}} collisions. In this article, the latest experimental electroweak data from hadron machines is reviewed. The author has taken a broad definition of a hadron machine to include the results from NuTeV ({nu}N collisions) and HERA (ep collisions) as well as the results of the Tevatron (p{bar p} collisions). This is not an exhaustive survey of all results, but a summary of the new results of the past year and in particular those results which have an influence on the indirect determination of the Higgs mass. This article will cover themore » direct determinations of the W boson and top quark masses from p{bar p} collisions at {radical}s = 1.8 TeV from the two Tevatron experiments, CDF and D0. These results are based on s-channel production of single W bosons and top quark pairs. The results presented here from the NuTeV and HERA experiments allow one to make complementary measurements and probe the electroweak interaction in the space-like domain up to large momentum transfers in the t-channel.« less
