A SPINOR TECHNIQUE IN SYMBOLIC FEYNMAN DIAGRAM CALCULATION

[摘要] We present a recursive diagrammatic method for evaluating tree-level Feynman diagrams involving multi-fermions which interact through gauge bosons (gluons or photons). Based on this method, a package cal led COMPUTE, which can generate and calculate all the possible Feynman diagrams for exclusive processes in perturbative QCD, has been developed (available in both Mathematica and Maple). As an example, a calculation of the nucleon Compton scattering amplitude is given. (C) 1994 Academic Press, Inc.
