The Top Mass at CDF and the Final Preparation for ATLAS

The measurement of the top quark mass is one of the flagship measurements to be performed at the Collider Detector at Fermilab (CDF). Indeed, a precise determination of this fundamental parameter of the Standard Model can be used to predict the Higgs boson mass that still eludes detection to date. I will present a precise measurement of the top mass that uses hadronic W boson decays to constrain the main systematic uncertainty of the measurement: the jet energy scale.



The attention of the hadron collider physics community is gradually shifting toward CERN where the first proton-proton collisions of the Large Hadron Collider (LHC) are expected in 2007. Intense activities are taking place to prepare the LHC experiments, like ATLAS, for the first period of data taking. I will present two examples of such activities in ATLAS: the final preparation of the pixel detector and the development of the data streaming model.
