Abstract

We compute the Script O sign(α_s³) inclusive cross section for the process pp→tt̄h in the standard model, at √s_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.
