Strategies for Higgs boson searches require the knowledge of the totalproduction cross section and the transverse momentum spectrum. The largetransverse momentum spectrum of the Higgs boson produced in gluon fusion can bequite different in the Standard Model and the Minimal Supersymmetric StandardModel. In this paper we present a comparison of the Higgs transverse momentumspectrum obtained using the PYTHIA event generator and the HIGLU program aswell as the program HQT, which includes NLO corrections and a soft gluonresummation for the region of small transverse momenta. While the shapes of thespectra are similar for the Standard Model, significant differences areobserved in the spectra of Minimal Supersymmetric Standard Model benchmarkscenarios with large tan(beta).Comment: 8 pages, 13 figure
