摘要

In this work we present a double extension to the Standard Model (SM). One of the extensions is introduced, via minimal coupling, generating a massive Z' boson. This enlarged SM is coupled to a dark matter sector through the Stueckelberg mechanism by a A' boson. However, the A' boson does not interact directly with the SM fermions. In our study, we found that the A' is a massless photon-like particle in dark sector. We obtain a new coupling between the usual photon and the dark fermions. Constraints are made on its values.
