Findings

Measurements agree with Standard Model predictions

Constraints on Higgs boson mass are derived

Updated W boson mass measurements included

Abstract

The status of published and preliminary precision electroweak measurements as of winter 2002/03 is presented. The new results on the mass of the W boson as measured at LEP-2 and on atomic parity violation in Caesium are included. The experimental results are compared with the predictions of the minimal Standard Model and are used to constrain its parameters, including the mass of the Higgs boson. The agreement between measurements and expectations from theory is discussed.
