Model description

We consider the effective interactions of a fermionic singlet dark matter particle with the SM hypercharge gauge boson field. The only non zero form factor operator for Majorana dark matter is the dimension-6 anapole moment, while for Dirac dark matter there exist the dimension-5 magnetic and electric dipole operators and the dimension-6 anapole and charge radius operators.

The detailed Lagrangian and more information can be found in arXiv:2005.XXXXX [hep-ph].

Description of the Model Files

    •, Main FeynRules model for the model, it already contains the SM Feynrules model.
  • UFO model files
    • EWFF4DM_UFO.tar.gz, Standalone LO UFO folder in the EWFF4DM models.

The actual files are provided in attachment.
