Query: NNLO corrections to the total cross section for Higgs boson production
  in hadron-hadron collisions   We present the next-to-next-to-leading order (NNLO) corrections to the total
cross section for (pseudo-) scalar Higgs boson production using an alternative
method than those used in previous calculations. All QCD partonic subprocesses
have been included and the computation is carried out in the effective
Lagrangian approach which emerges from the standard model by taking the limit
$m_t \to \infty$ where $m_t$ denotes the mass of the top quark. Our results
agree with those published earlier in the literature. We estimate the
theoretical uncertainties by comparing the $K$-factors and the variation with
respect to the mass factorization/renormalization scales with the results
obtained by lower order calculations. We also investigate the dependence of the
cross section on several parton density sets provided by different groups.
Further we study which part of the coefficient functions dominates the cross
section. This is of interest for the resummation of large corrections which
occur near the boundary of phase space. It turns out that depending on the
definition of the total cross section the latter is dominated by the the
soft-plus-virtual gluon corrections represented by $\delta(1-x)$ and
$(\ln^i(1-x)/(1-x))_+$ terms. PACS numbers: 12.38.-t, 12.38.Bx, 13.85.-t,
