Nature of physical 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.
Method of solution:
Feynman graphs are generated in a combinatorial method. The generated
code calculates Feynman amplitudes with spinor techniques.
Restrictions:
The program package is limited to the calculation of physical processes
in Born approximation.
Typical running time:
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.
