6 2) with the percentage extracted from Table 2 of [29], which is quoted as 4 . 9%. Our number is deficient in that it does not include NNLO corrections to the Higgs + 0 jet rate. Our calculation treats all jet bins consistently at NLO. The inclusion of the NNLO correction to the Higgs + 0 jet bin will reduce our number. On the other hand, the calculation of Ref. [29] is deficient because it does not treat all bins consistently at NNLO, i.e. it does not include NNLO corrections for the Higgs +1 jet rate or NLO+NNLO effects for the Higgs + ≥ 2 jet rate. We roughly estimate that including the NNLO effects in the Higgs +0 jet bin would move our central value from 11% to 10%. Overall, because the corrections are quite substantial, the theoretical estimate of the fraction of events in the Higgs + ≥ 2 jet bin is quite uncertain. Despite the fact that the fraction of events in the Higgs + ≥ 2 jet bin is small, it is important because the associated uncertainty is large. We investigate this issue in Table II, where we give the cross section for the process of Eq. (7) using a selection of values for the Higgs mass of current interest for the Tevatron. In the table we give the results for the leading order and next-to-leading order cross sections, calculated using LO and NLO MSTW2008 PDFs respectively. For the range of Higgs masses considered, the QCD corrections increase the cross section by approximately 40% (for the central value, µ = m$_{H}$ ). The theoretical error is estimated by varying the common renormalization and factorization scale in the range, m$_{H}$/ 2 < µ < 2 m$_{H}$ . As can be seen from the table, even though including the next- to-leading order corrections leads to a considerable improvement in the theoretical error, the remaining error is still quite sizeable. We do not include a factor to correct for the finite top mass, but in order to facilitate comparison with other calculations we also tabulate this factor m$_{H}$ [GeV] 150 160 165 170 180 Γ$_{H}$ [GeV] 0.0174 0.0826 0.243 0.376 0.629 σ$_{LO}$ [fb] 0 . 329 +92% − 45% 0 . 345 +92% − 44% 0 . 331 +92% − 44% 0 . 305 +92% − 44% 0 . 245 +91% − 44% σ$_{NLO}$ [fb] 0 . 447 +37% − 30% 0 . 476 +35% − 31% 0 . 458 +36% − 31% 0 . 422 +41% − 30% 0 . 345 +37% − 31% Finite m$_{t}$ correction, R 1 . 098 ± 0 . 003 1 . 113 ± 0 . 003 1 . 122 ± 0 . 004 1 . 130 ± 0 . 005 1 . 149 ± 0 . 005 TABLE II: Cross section for Higgs + 2 jet production and decay into W $^{−}$( → µ $^{−}$¯ ν ) W $^{+}$( → νe $^{+}$) at √ s = 1 . 96 TeV.
