Precise predictions for Higgs production in models with color-octet scalars


Boughezal, R; Petriello, F (2010). Precise predictions for Higgs production in models with color-octet scalars. Nuclear Physics B - Proceedings Supplements, 205-6:289-294.

Abstract

We describe an effective-theory computation of the next-to-next-to-leading order (NNLO) QCD corrections to the gluon-fusion production of a Higgs boson in models with massive color-octet scalars in the (8,1)_0 representation. Numerical results are presented for both the Tevatron and the LHC. The estimated theoretical uncertainty is greatly reduced by the inclusion of the NNLO corrections. Color-octet scalars can increase the Standard Model rate by more than a factor of two in allowed regions of parameter space.
