Standard Model

The SM is implemented for a diagonal CKM matrix at NLO QCD+EW. We provide the following variations:

  • SM: the SM in in the conventional ‘t Hooft Feynman gauge (NLO QCD+EW)

  • SM_BFM: SM in Background-Field Method (NLO QCD+EW)

  • SM_FERM: only fermionic loops (NLO QCD+EW)

  • SM_FERM_YUK: yukawa power-counting for the bottom and top quark (NLO QCD)

  • SM_NF5: removed top quark from modelfile (NLO QCD)

  • SM_NF4: removed top and bottom quark from modelfile (NLO QCD)

Field conventions

When defining processes one has to stick to the following particle/field names:
