摘要：
We present the most recent results for the measurement of the top quark mass at the CDF experiment of the Tevatron collider. The top mass has been measured in the dilepton (t (t) over bar -> ll + jets + E-T,l = e or mu) and lepton plus jets (t (t) over bar -> l + jets + E-T, l = e or mu) final !lessstates. In the lepton plus jets channel we obtain m(t) = 173.5(-2.6)(+2.7) (stat.) +/- 2.5(jet energy scale systematic) +/- 1.7(syst.) GeV/c(2), which is the most precise single top mass measurement in the world. A preliminary combination of the best measurements per decay channel from CDF and D0 experiments gives m(t) = 172.7 +/- 3.5 GeV/c(2).
