Threshold resummation in SCET vs. direct QCD: a systematic comparison

We perform a systematic comparison of soft-gluon resummation in SCET and in a standard “direct” QCD (dQCD) approach, both from an analytical and a phenomenological point of view. In particular, we concentrate on Higgs boson production in gluon-gluon fusion at a hadron collider. Using specifically a saddle point argument, we arrive at a detailed understanding of the quantitative differences between these two approaches.
