TOP QUARK MASS MEASUREMENTS
Measurements of the top quark mass from Run II of the Tevatron using integrated luminosities from 370 pb-1 to 1030 pb-1 are presented. Results from the CDF and DØ experiments in different channels are combined resulting in mt = 171.4 ± 2.1 GeV/c2. This corresponds to a relative uncertainty of 1.2%.
