Next-To-Next-To-Leading Order Qcdcorrections To Light Higgs Pair Production Via Vector Boson Fusion In The Type Ii Two-Higgs-Doublet Model
Physical Review D(2014)
Abstract
We present the precision predictions on the pair production of light, CP-even Higgs boson in weak vector boson fusion (VBF) up to the QCD next-to-next-to-leading order (NNLO) at hadron colliders within the CP-conserving type II two-Higgs-doublet model [2HDM(II)] by adopting the structure function approach. We investigate the model parameter dependence, residual uncertainties from the factorization/renormalization scale, PDFs, and alpha(s) on the integrated cross section at the QCD NNLO and find that the NNLO QCD corrections can reduce the scale uncertainty significantly. By analyzing the kinematic distributions of final Higgs bosons, we can extract the CP-even Higgs resonance via the H-0 -> h(0)h(0) channel as a means of probing the extension of the standard model (SM) Higgs sector.
