Abstract

The updated CDF measurement of the forward-backward asymmetry AFB in the top quark production pp-→tt- at Tevatron (with s=1.96 TeV) shows a deviation of 2 σ from the value predicted by the Standard QCD Model. We present calculation of this quantity in the scenario, where colored unparticle physics contributes to the s-channel of the process, and obtain the regions in the plane of the unparticle parameters λ and dU, which give the values of the AFB and of the total tt- production cross section compatible with the present measurements.
