A program to compute the Higgs boson transverse momentum spectrum,
d2 &sigma/(dpT dy),
at Next-to-Leading order (NLO) in QCD at hadronic colliders.
The production occurs via the top-quark loop diagram in the limit of
infinite top mass. Note that the computation is at non-zero pT
so that the leading order (LO) contribution to the distribution is at
The program may also be used to compute the LO distribution
for finite top quark mass. See Ref.  for details and results.
The distribution contains two distinct versions of the code:
HiggsPt is the basic version for producing
the transverse momentum distribution at fixed rapidity or the rapidity
distribution at fixed transverse momentum. A second version
HiggsPt_R produces output for use in
the transverse momentum resummation program RESBOS , on a grid in
Higgs mass, rapidity, and transverse momentum.
