There are many options which can be used in the block SPhenoInput in the Les Houches input file to set up the calculations and the output done by SPheno :

  • 1 sets the error level; default is 0

  • 7 if 1, skips two loop Higgs masses; default is 0
  • 8 Method to calculate two-loop corrections; default is 3
    • 1: fully numerical method
    • 2: semi-analytical method
    • 3: diagrammatic calculation
    • 8/9: using results from literature if available; 8 includes only corrections
  • 9 if 1, two-loop corrections are calculated in gauge-less limit; default is 1
  • 10 if 1, safe mode is used for the numerical derivative in the two-loop Higgs calculations; default is 0

  • 33 if set, a fixed renormalization scale is used
  • 34 sets the relative precision of the mass calculation; default is
  • 35 sets the maximal number of iterations in the calculation of the masses; default is 40
  • 36 sets the minimal number of iterations before SPhenostops because of tachyon in the spectrum; default is 5
  • 37 defines if CKM matrix is taken to be in the up- (1) or down- (2) quark sector; default is 1

  • 58 if 0, the calculation of in the boundary conditions at the SUSY scale is skipped; default is 1
  • 60 if 0, possible effects from kinetic mixing are neglected; default is 1

  • 76 if 1, input files for HiggsBoundsand HiggsSignalsare written; default is 1
  • 77 if 1, output is written to be used with MicrOmegas: running masses for light quarks are written instead of pole masses (necessary for the direct detection calculation) and real rotation matrices for Majorana fermions are used; default is 0
  • 86 sets the maximal width which is taken as ’invisible’ in the output for HiggsBoundsand HiggsSignals; default is 0.
  • 88 sets a maximal mass of particles which are included in loop calculations; default is  GeV. Note, this option must be turned in SARAHfirst
