SPheno Higgs production

SPheno provides an estimate for the production cross sections of all neutral scalars within a certain mass range:

• values for gluon-fusion and vector-boson fusion are obtained for m = \{50, 1000\} GeV
• ssociated production with W, Z and t are considered for m = \{50, 300\} GeV.

The results are obtained by re-weighting the SM cross sections with the effective coupling of the scalar in the model to SM states normalised to the SM values. For 7 and 8 TeV the SM cross-sections provided by the Higgs cross section working group are used, while for 13, 14 and 100 TeV the cross sections have been calculated with SusHi 1.5.0. The results are written into the spectrum file into the blocks HiggsLHCX (X=7,8,13,14) and HiggsFCC100

Remarks

The results will not show up if

• All masses are outside the fit range
• The calculation of the decays in SPheno is turned off (flag 11 put to 0), see SPheno flags

The involved scalar is indicated by it's PDG number. If the mass of a scalar is outside the range of the fit, it is not shown in the block.
