A systematic analysis of new physics effects in spin correlations in q qbar to t tbar

Abstract

I show that there are eight new physics operators that contribute to top pair production and subsequent decay in interference with the leading SM process at the Tevatron and estimate their expected statistical inaccuracies. All fully differential cross sections are calculated in the {6-particle} phase space. The observation of angular correlations dramatically improves the accuracy of the extraction.
