Threshold resummation at N 3 LL accuracy and soft-virtual cross sections at N 3 LO

We consider QCD radiative corrections to the production of colorless high-mass systems in hadron collisions. We show that the recent computation of the soft-virtual corrections to Higgs boson production at N 3 LO [1] together with the universality structure of soft-gluon emission can be exploited to...
