Abstract

The latest top quark mass measurements by the CDF and DØ~ experiments are presented here. The mass has been determined in the dilepton (\ttbar → eμ,ee,μμ + jets +\met) and lepton plus jets (\ttbar → e or μ + jets +\met) final states. The most accurate single result from lepton plus jets channel is 173.5^+3.7_-3.6(stat. + Jet Energy Scale Systematic)±1.3(syst.) ~GeV/c², which is better than the combined CDF and DØ~ Run~I average. A preliminary and unofficial average of the best experimental Run~II results gives M_top = 172.7±3.5 GeV/c².
