=== <a name="Description_of_the_model"></a> 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.
