Nature of problem:
This program package automatically generates a set of programs which is necessary for the calculation of the cross section and generation of simulated events in accordance with the specification of a physical reaction in the standard or minimus supersymmetric model.
Feynman graphs are generated in a combinatorial method. The generated code calculates Feynman amplitudes with spinor techniques.
The program package is limited to the calculation of physical processes in Born approximation.
It takes 10 seconds on IBM RS/6000 SP for code generation and compilation of generated code for 2 --> 3 MSSM process with 28 Feynman graphs and it takes 146 seconds for the integration over phase space for the same process.
