A. Weak boson fusion 9 As noted above, the process studied in this paper produces the same final state as expected from Higgs production via weak boson fusion (WBF). Although the electroweak process is It is also interesting to consider the dependence of the cross section on the minimum transverse momentum required for the observed jets. Results for several other values of this threshold, either side of our default value of 40 GeV, are shown in Table IV. As can be seen from the table, the percentage effect of the NLO corrections on the total rate is practically independent of the value of p min t (jet) in the range studied. For the sake of illustration we have chosen m$_{H}$ = 160 GeV in the study above. To illustrate the effect of the QCD corrections more broadly, in Table III we give the cross sections for Higgs masses in the range 120 GeV < m$_{H}$ < 200 GeV. It is within this range that the Higgs + 2 jet process considered here is of most interest, due to its interplay with the electroweak weak boson fusion channel. We observe that the effect of the QCD corrections increases from about 5% for m$_{H}$ = 120 GeV to 21% for m$_{H}$ = 200 GeV. Estimating the theoretical error in the same way as before, we see that the uncertainty is slightly less at the LHC than at the Tevatron. for Higgs + 2 jets ( m$_{H}$ = 160 GeV) in Figure 2. We have also checked the agreement of our $_{calculation with previous results [12] at}$√$_{s}$ = 14 TeV, taking into account the different choice of parton distribution functions used in that reference. As noted in the earlier paper [12], the corrections are quite modest using our central scale choice, µ$_{0}$ = µ$_{H}$ , increasing the cross section by approximately 15%. Once again, although the scale dependence is much reduced it is still substantial. m$_{H}$ [GeV] 120 140 160 180 200 Γ$_{H}$ [GeV] 0.0036 0.0083 0.0826 0.629 1.426 σ$_{LO}$ [pb] 1 . 88 +78% − 40% 1 . 48 +76% − 40% 1 . 20 +75% − 40% 0 . 98 +74% − 39% 0 . 81 +73% − 39% σ$_{NLO}$ [pb] 1 . 98 +20% − 23% 1 . 63 +22% − 23% 1 . 36 +23% − 23% 1 . 15 +24% − 23% 0 . 98 +25% − 24% Finite m$_{t}$ correction, R 1 . 060 ± 0 . 002 1 . 084 ± 0 . 003 1 . 113 ± 0 . 004 1 . 149 ± 0 . 005 1 . 191 ± 0 . 007 TABLE III: Cross section and uncertainties for Higgs + 2 jet production at √ s = 10 TeV with the cuts of Eq.
