Does the new version supersede the previous version?: No

Nature of problem:
Study of the properties of N = 1 supersymmetric field theories using the superfield formalism, derivation of the associated Lagrangians.

Solution method:
We use the FeynRules package and define internally the N = 1 superspace. Then, we implement a module allowing to:
  1. Perform the Grassmann variable series expansion so that any superfield expression can be developed in terms of the component fields. The resulting expression is thus suitable to be treated by the FeynRules package directly.

  2. Execute a set of operations associated to the superspace, such as the superderivatives of an expression or the calculation of its supersymmetric transformation laws.

Reasons for new version:
This is an interim update to the FeynRules-1.4, (AEDI_v1_0), package which includes a new superspace module. Further modules will be added in the future and eventually published as FeynRules-1.6.

Summary of revisions:
This revised version contains, in addition to the core program, the superfield module of FeynRules.

Superfields related to spin 3/2 and 2 particles are not implemented.

Unusual features:
All calculations in the internal routines are performed completely. The only hardcoded core is the Grassmann variable algebra.

Running time:
It depends on the user's purposes. The extraction of a Lagrangian in terms of the component fields may take a few minutes for a complete model with complex mixing between the fields.
