【 摘 要 】

The interactions of the top quark will soon be coming under greater scrutiny at CDF with Run II of the Fermilab Tevatron collider. This investigation gauges CDF's improved ability to measure the helicity of W bosons produced in top quark decays. Such measurements will provide a direct indication of the spin structure of the weak interaction responsible for the top decay process. Simulated CDF Run II data is used to study the W helicity sensitivity of the muon momentum in (mu) + jets events, as limited by both statistical and systematic uncertainties. Optimization of helicity measurements via appropriate choices of event variables and data criteria is also addressed.
