Nature of problem:
Symbolic calculation of QED tree diagrams with the help of the spinor product method.

Solution method:
(i) All tree diagrams of a given QED process are automatically generated. (ii) According to all Feynman diagrams and all polarizations of the external particles, the program generates the input for a REDUCE program to calculate the amplitudes analytically.

Six external fermions and nine external bosons

Running time:
A few mintues for problems with six external particles
