Symbolic Analysis of Feynman Diagrams by Computer

摘要

The paper describes a system of programs in the language LISP 1.5 which handles all stages of calculation from the specification of an elementary-particle process in terms of a Hamiltonian of interaction or Feynman diagrams to the derivation of an absolute square of the matrix element for the process. Examples of significant parts of the programs are presented in the text. (Author)
