Description of the model
This model is an extension of the SM, including additional interaction of fermions to a W' boson following the lowestorder effective Lagrangian described in Refs. [1] [2]:
where g'_{R,L} are the righthanded (lefthanded) W'boson gauge couplings to fermions f_{i} and f_{j}, and V'_{ij} is either the CKM matrix or a diagonal matrix, for quarks and leptons respectively.
Model files
 weff.fr: the main model file.
 WEff.nb: example of Mathematica notebook that loads the model, calculates the Feynman rules and extract the model files within the UFO format.
 weff.ufo.tgz: The model files in UFO format (for MadGraph 5).
Notes:
 The W'boson mass and width are set using the parameters MWp and WWp, respectively
 The lefthanded (righthanded) W'boson couplings to quarks and leptons are given by the matrices CLq and CLl (CRq and CRl) respectively.
By default CLq and CRq are set to the CKM values and CLl and CRl are set to identity.  The lefthanded and righthanded W'boson coupling constants are set by the parameters gL and gR.
By default these values are set at 0.1.
