Next-to-leading order results for tt macro h production at the Tevatron

We compute the Omicron(alpha(3)(s)) inclusive total cross section for the process pp macr0 -->tt macro h in the standard model, at the square root of s(H) = 2 TeV. The next-to-leading order corrections drastically reduce the renormalization and factorization scale dependence of the Born cross section and slightly decrease the total cross section for renormalization and factorization scales between m(t) and 2m(t).
