【 摘 要 】

We examine the models of new physics which could potentially explain the significant deviation of the measured forward-backward asymmetry in t production at the Tevatron from the SM prediction, by fitting the models to the all available t production data. To be able further to discriminate among the NP models we calculate predictions for various top spin polarization and top-antitop spin correlation observables at Tevatron and the LHC.
