We study the application of the joint resummation formalism to Higgs boson production via gluon-gluon fusion at the CERN LHC, defining inverse transforms by analytic continuation. We work at next-to-leading logarithmic accuracy. We find that at low QT the resummed Higgs QT distributions are comparable in the joint and pure-QT formalisms, with a relatively small influence from threshold enhancement in this range. We find a modest (about ten percent) decrease in the inclusive cross section, relative to pure threshold resummation.
