ggH contamination in VBF phase space

The technique of the study

The gluon fusion Higgs production enters the VBF phase space because of perturbative effects of the Higgs + 0jets generation, and because of higher order diagrams. A calculation is being performed with MCFM for the contribution of Higgs + 2jets at NLO, after the selections listed here below.

selections applied

cut CMS ATLAS common
tag jets higest pT higest pT higest pT
jets num 2 jets w pT > 30 GeV 2 jets w pT > 25 GeV  
jets eta < 4.5 < 4.5 < 4.5
Deta_jj > 3.5 > 3.8  
M_jj > 450 GeV > 500 GeV  
etaProd_jj -- >0  
additional jets veto no jets with pT > 30 GeV between tag jets no jet with pT > 25 GeV and eta < 3.2  
leptons pT 20, 10 GeV 25, 15 GeV  
leptons eta < 2.5 < 2.5 < 2.5
