Next-to-leading order QCD corrections to pp→t(t)over-barh at the CERN Large Hadron Collider -: art. no. 071503

We compute the O(alpha(s)(3)) inclusive cross section for the process pp-->t (h) over barh in the standard model, at roots(H)=14 TeV. The next-to-leading order corrections drastically reduce the renormalization and factorization scale dependence of the Born cross section and increase the total cross section for renormalization and factorization scales larger than m(t). These corrections have important implications for models of new physics involving the top quark.
