     1==Model description==
     2
     3The 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

     5 [[latex( $\mathcal{L}_{X} = \mathcal{L}_{X,\text{kin}}+\epsilon^{\mu\nu\alpha\beta}\left(W_{\mu}X_{\nu}\partial_{\alpha}WY{\dagger}_{\beta}+\text{h.c.} + c_{Z}Z_{\mu}X_{\nu}\partial_{\alpha}Z_{\beta}+c_{Z\gamma}Z_{\mu}X_{\nu}\partial_{\alpha}A_{\beta}\right) )]]

     11==Implementation description==
     12
     13The 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 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.
