SM Higgs production cross sections at √s = 13, 14 and 27 TeV (update in CERN HL-LHC YR 2019)
Cross sections are computed for m
H=125.09
GeV by using the YR4 input parameters. More details can be found on the
LHCHXSWG-INT-2019-0xx note and in Sec. 2.2 of the
HL-HE report.
Gluon fusion
Cross sections are calculated at N3LO QCD and NLO EW accuracy using the program iHixs.

Vector boson fusion
Cross sections are calculated at NNLO QCD with the program proVBFH while the EW and photon contributions have been computed at NLO with HAWK.
The reference cross section is σ = σDIS*(1+deltaELWK)+σγ
