Model description

The 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, $\gamma$, via pseudo Chern-Simons current. After acquiring the Higgs VEV, the interaction has the form [1][2]

Implementation and usage description

The model has been implemented using merging of SM.fr and Chern-Simons-Portal.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.

To use the model, unpack the ChernSimons_UFO.zip archive and move the resulting folder ChernSimons_UFO to the directory /models of your MadGraph directory.
