New physics in ttbar spin correlations at the Tevatron

High Energy Physics - Phenomenology 2011-03-23 v2

Abstract

We show that the angular distributions of leptons or jets due to ttbar spin correlations allow a determination of the top chromomagnetic moment kappa with an accuracy of order 0.1. The method is quite insensitive to background, event reconstruction, and other experimental uncertainties. The total event number is important, so we suggest the inclusion of all-hadronic events.
