Current recommendations for HH cross-sections

Changed:

Inclusive cross sections for Higgs boson pair production are reported below for different centre-of-mass energies in NNLO FTapprox, for mH = 125 GeV with the central scale μ0 = μR = μF = MHH/2 (see https://arxiv.org/abs/1803.02463). Scale uncertainties are obtained by probing six relative variations of μR and μF on top of the central one, i.e. (0.5;0.5), (0.5;1), (2;1), (1;1), (1;2), (1;0.5), (2;2): they are reported as superscript/subscript below. PDF uncertainties are estimated within the Born-improved approximation and are based on the PDF4LHC15nnlomc set. The calculation is performed in the on-shell top-quark mass scheme. The uncertainties related to missing finite top-quark mass effects within this approximation are also presented (mtop unc.). The uncertainties related to the renormalization scheme and scale of the top-quark mass are not included for the moment, and studies aimed at estimating their size are in progress.

 The table below shows NNLL-matched-to-NNLO cross-sections for gg → HH with the central scale μ0 = μR = μF = MHH/2, including top-quark mass effects at NLO. Uncertainties are evaluated using the PDF4LHC recommendation and are based on the PDF4LHC15nnlomc set. The theoretical uncertainty of 5% is related to missing finite top-quark mass effects. Prior to r27 of this twiki page, the recommended cross-sections at 13 and 14 TeV were under-estimated by a few per-mille with respect to those published in the YR4.

These are only to be used for publications related to the 2015+2016 dataset... neither for end-of-Run-2 papers nor for projections!

Current recommendations for HH cross-sections

Inclusive cross sections for Higgs boson pair production are reported below for different centre-of-mass energies in NNLO FTapprox, for mH = 125 GeV with the central scale μ0 = μR = μF = MHH/2 (see https://arxiv.org/abs/1803.02463). Scale uncertainties are obtained by probing six relative variations of μR and μF on top of the central one, i.e. (0.5;0.5), (0.5;1), (2;1), (1;1), (1;2), (1;0.5), (2;2): they are reported as superscript/subscript below. PDF uncertainties are estimated within the Born-improved approximation and are based on the PDF4LHC15nnlomc set. The calculation is performed in the on-shell top-quark mass scheme. The uncertainties related to missing finite top-quark mass effects within this approximation are also presented (mtop unc.). The uncertainties related to the renormalization scheme and scale of the top-quark mass are not included for the moment, and studies aimed at estimating their size are in progress.

Latest recommendations for gluon fusion (for end-of-Run-2 analyses)

 Inclusive cross sections for Higgs boson pair production are reported below for different centre-of-mass energies in NNLO FTapprox, for mH = 125 GeV with the central scale μ0 = μR = μF = MHH/2 (see https://arxiv.org/abs/1803.02463). Scale uncertainties are obtained by probing six relative variations of μR and μF on top of the central one, i.e. (0.5;0.5), (0.5;1), (2;1), (1;1), (1;2), (1;0.5), (2;2): they are reported as superscript/subscript below. PDF uncertainties are estimated within the Born-improved approximation (see https://arxiv.org/abs/1309.6594). The calculation is performed in the on-shell top-quark mass scheme. The uncertainties related to missing finite top-quark mass effects within this approximation are also presented (mtop unc.). The uncertainties related to the renormalization scheme and scale of the top-quark mass are not included for the moment, and studies aimed at estimating their size are in progress.

The table below shows NNLL-matched-to-NNLO cross-sections for gg → HH with the central scale μ0 = μR = μF = MHH/2, including top-quark mass effects at NLO. Uncertainties are evaluated using the PDF4LHC recommendation and are based on the PDF4LHC15nnlomc set. The theoretical uncertainty of 5% is related to missing finite top-quark mass effects. Prior to r27 of this twiki page, the recommended cross-sections at 13 and 14 TeV were under-estimated by a few per-mille with respect to those published in the YR4.

OLD recommendations for gluon fusion (from YR4)

The table below shows NNLL-matched-to-NNLO cross-sections for gg → HH with the central scale μ0 = μR = μF = MHH/2, including top-quark mass effects at NLO. Uncertainties are evaluated using the PDF4LHC recommendation and are based on the PDF4LHC15nnlomc set. The theoretical uncertainty of 5% is related to missing finite top-quark mass effects.

These are only to be used for publications related to the 2015+2016 dataset... neither for end-of-Run-2 papers nor for projections!

Inclusive cross sections for Higgs boson pair production for different centre-of-mass energies in the NNLOFTapprox, for mH = 125 GeV (see https://arxiv.org/abs/1803.02463). Scale uncertainties are reported as superscript/subscript. PDF uncertainties are estimated within the Born-improved approximation (see https://arxiv.org/abs/1309.6594). The estimated top-quark mass uncertainty of the NNLOFTapprox predictions is also presented, together with PDF and αS uncertainties. The calculation is performed in the on-shell top-quark mass scheme, and studies of the uncertainty related to the scheme choice are in progress.

The cross-sections have been obtained by de Florian and Mazzitelli (as in 1309.6594 and 1408.2422.) at NNLO using EFT.

Central scale μ=mHH. CT10 PDF set was used.

Preliminary PDF uncertainties are the envelope of the central values from CT10, NNPDF 3.0, and MSTW. Final PDF uncertainties will be found after the PDF4LHC recommendation in early 2015.

The following parameters have been used:

mh = 126 GeV, mt = 173.18 GeV, mb = 4.75 GeV.

    The cross-sections have been obtained by de Florian and Mazzitelli (as in 1309.6594 and 1408.2422.) at NNLO using EFT.

    Central scale μ=mHH. CT10 PDF set was used.

    Preliminary PDF uncertainties are the envelope of the central values from CT10, NNPDF 3.0, and MSTW. Final PDF uncertainties will be found after the PDF4LHC recommendation in early 2015.

    The following parameters have been used:

    mh = 126 GeV, mt = 173.18 GeV, mb = 4.75 GeV.
