=== Model Implementation ===
Details about this implementation can be found in the reference above. Additionally, the [http://feynrules.irmp.ucl.ac.be/ FeynRules] automatic output for this model can be found here:

=== Instructions ===
We provide a basic notebook giving examples of how to run the [http://feynrules.irmp.ucl.ac.be/ FeynRules] interfaces on this model:

=== Interfaces ===
This model implementation is known to work with [http://theory.sinp.msu.ru/~pukhov/calchep.html CalcHEP]. The CalcHEP files can be found here:

This model has not been tested with [http://madgraph.hep.uiuc.edu/ MadGraph 5] but works in principle.
=== Validation ===
The Feynman rules were computed by hand and compared with the [http://feynrules.irmp.ucl.ac.be/ FeynRules] vertices and found to agree. Furthermore, the squared amplitudes for several Drell-Yan processes were calculated by hand and compared with the analytic output of CalcHEP and found to agree.
