Precision Standard Model Measurements at the Tevatron

摘要

The CDF and D? collaborations at the Tevatron have produced exquisite precision measurements on high-P_T physics with their large datasets of p~p collisions. The top quark is being studied in great detail, and a precision of 1.1% in the measurement of its mass has been achieved. The large datasets of W and Z boson decays have allowed the most precise measurement of the W mass to date;; moreover, associated production of pairs of vector bosons have been observed and measured. The precise knowledge of top and W masses is providing decisive new input for the allowed mass range of a standard model Higgs boson, as well as for the parameter space of benchmark scenarios in supersymmetric theories.
