Model Implementation

Details about this implementation can be found in the reference above. Additionally, the FeynRules automatic output for this model can be found here:

• SM-DY.pdf: Fields, parameters, Lagrangians and Vertices.

Instructions

We provide a basic notebook giving examples of how to run the FeynRules interfaces on this model:

• SMplus.nb.gz

Interfaces

This model implementation is known to work with the following interfaces:

• CalcHEP/CompHEP Interface
• MadGraph Interface (It should work but has not been tested.)

Validation

The Feynman rules were computed by hand and compared with the 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.
