摘要
The LanHEP program is aimed for Feynman rules generation in momentum representation. It reads the Lagrangian written in the compact form close to one used in publications, when summations over indices of broken symmetries and special symbols for complicated expressions are introduced. The output is Feynman rules in terms of physical fields and independent parameters, it can be written in LaTeX format and in the form of CompHEP [1] model files, which allows one to start calculations of processes in the new physical model. The program allows one to introduce into CompHEP new gauge theories as well as various anomalous terms.
