Erratum to “The Tevatron Higgs exclusion limits and theoretical uncertainties: A critical appraisal” [Phys. Lett. B 699 (2011) 368]

摘要

After our paper [1] had appeared in Physics Letters B, we realised that an error occurred in the numerical analysis which had led to Fig. 1 for theproduction cross section when the four NNLO PDF sets are adopted. In the plot with the two HERAPDF sets, the central scales at whichhas been evaluated were not set toas it should have been, but atwhich gives the minimal cross section once the scale uncertainty is included. This explains the large difference in the cross section,1 up to 40%, between the MSTW and HERAPDF predictions. We thus present our mea culpa and produce in Fig. 1 the correct figure where all scales are consistently set to. The difference between the MSTW and HERAPDF predictions reduces now toat most, which is indeed much more reasonable. In this case, the smallest value of the cross section is given when using the ABKM set and amounts toin the considered Higgs mass range as noticed in Ref. [2] (this difference is slightly larger if the new ABM10 PDF set is used [3]). Note that the same analysis presented for the LHC in Ref. [4] is not affected by this problem.
