Web10 mei 2016 · We present the most precise value for the Higgs boson cross-section in the gluon-fusion production mode at the LHC. Our result is based on a perturbative expansion through N3LO in QCD, in an effective theory where the top-quark is assumed to be infinitely heavy, while all other Standard Model quarks are massless. We combine this result with … Web5 feb. 2024 · The cross sections for H +\ge 1 jet, Z +\ge 1 jet, and dijet production from NNLOJET are shown in Fig. 3, as a function of the inclusive jet p_T at LO, NLO and NNLO. The figure shows representative values for R\in [0.3,0.5,0.7,1.0] to illustrate the spread induced on the cross section.
