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

We consider Higgs boson production by gluon fusion in hadron collisions. We study the doubly-differential transverse-momentum (qT) and rapidity (y) distribution of the Higgs boson in perturbative QCD. In the region of small qT (qT ≪ MH, MH being the mass of the Higgs boson), we include the effect of...
