We estimate that stringent constraints on the color-octet scalar parameters can be obtained using the Tevatron exclusion limit... | We compute the next-to-next-to-leading order QCD corrections to the gluon-fusion production of a Higgs boson in models with massive color-octet scalars in the ${\bf (8,1)_0}$ representation using an effective-theory approach.
