Abstract
We consider the gluon fusion production cross section of a scalar Higgs boson
in models where fermion and scalar massive colored
particles are present. We report analytic expressions for the matrix elements
of gg → Hg, q
→ Hg, and qg → Hq processes completing
the calculation of the NLO QCD corrections in these extended scenarios.
The formulas are written in a complete general case,
allowing a flexible use for different theoretical models.
Applications of our results to two different models are presented: i)
a model in which the SM Higgs sector is augmented by a weak doublet scalar
in the SU(Nc) adjoint representation. ii) The MSSM,
in the limit of neglecting the gluino contribution
to the cross section.
