Top Quark Mass Measurement at the CDF Experiment

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 (, l=e or μ) and lepton plus jets (, l=e or μ) final !lessstates. In the lepton plus jets channel we obtain , 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 DO experiments gives .
