The HITRAN2020paper describing the new edition is available in Open Access

The top mass approximation uncertainty reported in the last row should not be considered in analyses since it is expected to be covered by the larger mtop scheme uncertainty.The data on this website corresponds to the HITRAN2020 edition of the database. The recommended uncertainties to be considered are PDF, alphaS (combined " PDF+αS unc."), scale and mtop scheme (combined " Scale+mtop unc."). The uncertainties related to missing NNLO finite top-quark mass effects within the FT approximation are also presented (mtop approx.

PDF uncertainties are estimated within the Born-improved approximation and are based on the PDF4LHC15nnlomc set. Uncertainties arising from the choice of renormalization scheme and scale of the top-quark mass (mtop scheme+scale unc.) and their combination with μR and μF variations (comb. Scale uncertainties are obtained by probing six relative variations of μR and μF on top of the central one, i.e. 11 (2022)Ĭurrent recommendations for HH cross-sectionsġ) Inclusive ggF cross sections for Higgs boson pair production are reported below for different centre-of-mass energies in NNLO FTapprox, for m H = 125 GeV with the central scale μ0 = μR = μF = M HH/2 (see ).
