Discerning new physics in tt-production from the top spin observables

Several top spin observables and the recent top spin correlation measurement by ATLAS is used to consider the consistency of the simplified single-resonance models and to provide a significant constraint on possible explanations of the Tevatron forward-backward asymmetry anomaly. It was shown that future precise measurements of top spin correlations and especially top polarization could differentiate between scalar t-channel models, while they are less sensitive to pure s-channel contributions.
