HiggsPt version 1.2

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 &alphas3. The program may also be used to compute the LO distribution for finite top quark mass. See Ref. [1] 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 [2], on a grid in Higgs mass, rapidity, and transverse momentum.

  5. The program uses the LHAPDF (Les Houches Accord PDF) interface to access various up-to-date parton distribution function sets. More information on downloading the LHAPDF libraries and the various PDF sets can be found at http://hepforge.cedar.ac.uk/lhapdf/.
