Abstrakt: | Some distributions of the in the top-quark pair production reaction pp ! bu d b at the LHC are calculated to leading order in the presence of the anomalous Wtb coupling with operators of dimension up to five. The distributions in the transverse momentum, rapidity and cosine of the angle with respect to the beam in the laboratory frame and with respect to the reversed momentum of the b-quark in the rest frame of W-boson are changed rather moderately by the anomalous Wtb coupling. The distributions computed with the full set of leading order Feynman diagrams practically do not differ from those computed with the t t production diagrams, with typical acceptance cuts. This demonstrates very little effect of the off-resonance background contributions. |
