Title: The Top Quark Forward-Backward Asymmetry and Top Production at the Tevatron

Abstract:

A method of fully reconstructing top-antitop events in the lepton plus jets mode has been developed. The method is applied to a measurement of the Top quark forward backward asymmetry using 300 top-antitop pairs recorded in 700 pb-1 of proton-antiproton collisions recorded with the CDF-II . The measurement is a test of discrete symmetries in strong interactions. In the present data set it is potentially sensitive to large parity violating contributions to top production from a massive Z' boson. Larger data sets will have sensitivity for an interesting charge conjugation asymmetry arising from pure QCD at NLO. Several additional tests of Top Production are investigated using the method developed.
