2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/194693We report on the calculation of the next-to-leading order QCD corrections to the production of top--anti-top quark pairs in association with a hard jet at the Tevatron and at the LHC. We present results for the t tbar + jet cross section and the forward--backward charge asymmetry. The corrections stabilize the leading-order prediction for the cross section. The charge asymmetry receives large corrections.4 pagesHigh Energy Physics - Phenomenologytext
