Abstract
Recent measurements of the mass of the top quark (t) are presented using 162 pbâ1 of data of pp¯ collisions at s=1.96 TeV collected by the CDF detector at the Tevatron collider during Run II. The analyses focus on the semi-leptonic decay mode tt¯â(blν)(b¯qq¯) with one or two identified bottom quarks (b). The Template Method reconstructs the invariant mass of the top quark in each event. The Multivariate Template Method enhances this approach by adding information on the event topology. The Dynamical Likelihood Method discriminates between possible mass values using top quark decay observables and attempts to use the maximum amount of information on top quarks provided by the Standard Model. All three methods produce similar results. The Dynamical Likelihood Method yields a top quark mass of 177.8â5.0+4.5(stat)±6.2(sys) GeV/c2.
