Description
I will describe how approximate higher order results can be obtained from known asymptotic regimes, in turn determined by all-order resummed expressions. Specifically, threshold (large-x) resummation combined with high-energy (small-x) resummation can lead to reliable determinations of inclusive N3LO cross sections such as those of Higgs, $t\bar t$ or Drell-Yan productions. The method is validated against known lower-order results, and includes an estimate of the uncertainty associated with the approximation itself.
