  We consider the transverse-momentum distribution of a Higgs boson produced
through gluon fusion in hadron collisions. At small transverse momenta, the
large logarithmic terms are resummed up to next-to-leading-logarithmic (NLL)
accuracy. The resummed computation is consistently matched to the
next-to-leading-order (NLO) result valid at large transverse momenta. The
ensuing Standard Model prediction is supplemented by possible new-physics
effects parametrised through three dimension-six operators related to the
modification of the top and bottom Yukawa couplings, and to the inclusion of a
point-like Higgs-gluon coupling, respectively. We present resummed
transverse-momentum spectra including the effect of these operators at NLL+NLO
accuracy and study their impact on the shape of the distribution. We find that
such modifications, while affecting the total rate within the current
uncertainties, can lead to significant distortions of the spectrum. The proper
parametrization of such effects becomes increasingly important for experimental
analyses in Run II of the LHC.
