    88=== Description of the model ===
    … …  
    1010The BSM Characterisation (BSMC) model is an extension of the [/wiki/HiggsCharacterisation Higgs Characterisation (HC)] model and is based on the Standard Model (SM) effective-field-theory (EFT) Lagrangian in the mass-eigen basis.

    12 We adopt the notation of the Lagrangian in the Higgs basis proposal for LHC HXSWG and additionally consider all couplings external parameters that can be tuned according to the needs of the user. More information on the parameterization can be found on [https://twiki.cern.ch/twiki/bin/view/LHCPhysics/LHCHXSWGEFTbases the HXSWG page]. All the coefficients of the operators in the BSMC model are hence implemented as external parameters in the !FeynRules implementation (i.e. independent parameters), although a large fraction of them are dependent as soon as one considers a gauge-invariant set of independent operators in the SM EFT, as done e.g. in the Warsaw or SILH bases. The translation of the coefficients from those bases to the Higgs basis can be done by [http://www.sussex.ac.uk/tpp/research/heptools Rosetta], and an output parameter card from Rosetta can be used as an input card for FeynRules and for event generators (e.g. MadGraph5_aMC@NLO), with the BSMC model file.
