    7 The Chern-Simons portal adds a new vector particle with zero electric charge, the X boson, interacting with the Standard Model gauge bosons - W, Z, [[latex( $\gamma$ )]] via pseudo Chern-Simons current. The low energy effective interaction has the form [#ref1 [1]][#ref2 [2]]
     7The Chern-Simons portal extends the Standard Model by adding a new vector particle with zero electric charge, the X boson, interacting with the Standard Model electroweak gauge bosons, W, Z, [[latex( $\gamma$ )]], via pseudo Chern-Simons current. After acquiring the Higgs VEV, the interaction has the form [#ref1 [1]][#ref2 [2]]

    1616== Implementation and usage description
    1717
    18 The model has been implemented using merging of SM.fr and ChernSimons.fr files. The implementation introduces one real new vector particle - X boson with the name xb. The implementation contains 6 new parameters: the coupling to W bosons cW (default value: 0.001), the coupling to Z bosons cZ (default value: 0.001), the coupling to the Z boson and photon cZgamma (default value: 0.001), the non-minimal axial-vector coupling to muons Cmu (default value: 0.1), the X boson mass Mxb (default value: 1 in units of GeV), the X boson width Wxb (default value: 1 in units of GeV). The implementation is performed in the unitary gauge. The implementation format is the UFO format.

    23 === Model files
    24 * ChernSimons.fr : this is the main file.
    25 * ChernSimons.nb : this is an example Mathematica notebook that loads the model, calculates Feynman rules and makes the UFO implementation. Note that it requires the implementation of the model file of the SM implementation of FeynRules.
