Jean-Francois Arguin University of Toronto Prospects for Measuring the Top Quark Mass in CDF Run II (Jean-Francois Arguin, P.K. Sinervo) The top quark mass is currently one of the most important parameters to be measured in particle physics. Together with the W boson mass, its value constrains the Higgs boson mass, the last particle of the Standard Model yet to be discovered. The Run II CDF and DZero experiments offer the opportunity to improve the current knowledge of the top quark mass with an upgraded accelerator and detectors. I will discuss the prospects for improvement of this measurement using the CDF detector, and present the work carried out at the University of Toronto in this direction. I will emphasize the importance of the jet energy calibration.
