Top Mass Measurements at the Tevatron Run II
The latest top quark mass measurements by the CDF and DØ~ experiments are presented here. The mass has been determined in the dilepton ($\ttbar \to eμ,ee,μμ$ + jets +$\met$) and lepton plus jets ($\ttbar \to e$ 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)$\pm1.3$(syst.) ~GeV/c$^{2}$, 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 $M_{top}$ = $172.7\pm3.5$ GeV/c${^2}$.
