  We present the results of our recent study (arXiv:1510.08850) of the
theoretical uncertainties that affect the predictions for the Higgs-boson
transverse-momentum in gluon fusion when fixed- and all-order results are
matched. Our investigation consists of a twofold analysis: first we present a
detailed comparison of two recently introduced prescriptions for the
determination of the matching scale (arXiv:1409.0531, arXiv:1505.00735), then
we apply the results of these methods to three widely used matching frameworks,
namely the aMC@NLO and POWHEG Monte Carlo approaches and analytic resummation.
The results of our study are applied to the production of the SM Higgs boson
and of the neutral Higgs bosons of the Two-Higgs-Doublet Model in a variety of
scenarios.
