Ian Vollrath University of Toronto Improving W Boson Mass Templates for Run II at CDF With center of mass energy of 1.96 TeV the Tevatron collider at Fermilab is currently the highest energy collider in the world. Over the course of Run II the CDF detector is expected to measure the W boson mass with a precision of approximately 40 MeV. This presents new challenges in the Monte Carlo generation of W boson mass templates. Currently there is no full calculation that incorporates both QCD and electroweak corrections to the W mass, however, there are separate calculations that deal with these quantities. This talk presents the results of a numerical method of merging these calculations. The implications on the Run II W mass measurement will be discussed.
