Transverse-momentum resummation: Higgs boson production at the Tevatron and the LHC

We consider the transverse-momentum (qT ) distribution of Standard Model Higgs bosons produced by gluon fusion in hadron collisions. At small qT (qT < m H , m H being the mass of the Higgs boson), we resum the logarithmically-enhanced contributions due to multiple soft-gluon emission to all o...
