Description of the model

The Hidden Abelian Higgs Model consists in the standard model extended by a new U(1) gauge symmetry, broken by a new Higgs field. The SM fields are singlets under the new gauge group, and they only couple to the new sector through mixing effects in the gauge and scalar sectors. The particle content and the vertices of the model are summarized in the following pdf file.

Model files

  • Hidden.fr: This is the main file.
  • Hidden.nb: This is an example Mathematica notebook that loads the model and calculates Feynman rules.

Instructions

The model-file is loaded in the usual way.

Feynman gauge is not supported, only unitary gauge is available.

Matrix element generator files

Below we give tarballs containing the model files generated by FeynRules for the various matrix element generaotrs for which a FeynRules interface exists. All fermion masses are put to zero, except for the top, the bottom and the Tau lepton masses. All files are in unitary gauge.
