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 ​CalcHEP. The CalcHEP files can be found here:

• SM-DY-CH.tgz

This model has not been tested with ​MadGraph 5 but works in principle.

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.
