SM Higgs production cross sections at √s = 13, 14 and 27 TeV (update in CERN HL-LHC YR 2019)

Cross sections are computed for mH=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 (approx.) NNNLO QCD and NLO EW accuracy using the program iHixs.

27 146.65 pb 4.53% 6.43% 1.95% 2.69% 2.64%

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
