Manuscript Title: LanHEP - a package for the automatic generation of Feynman rules in field theory Version 3.0 | ||

Authors: A.V. Semenov | ||

Program title: LanHEP | ||

Catalogue identifier: AECH_v1_0Distribution format: tar.gz | ||

Journal reference: Comput. Phys. Commun. 180(2009)431 | ||

Programming language: C. | ||

Computer: PC. | ||

Operating system: Linux. | ||

RAM: 2MB (SM) - 12MB (MSSM) - 120MB (MSSM with counterterms) | ||

Keywords: Feynman rules. | ||

PACS: 11.10.-z. | ||

Classification: 4.4. | ||

Nature of problem:Deriving Feynman rules from the Lagrangian. | ||

Solution method:The program reads the Lagrangian written in a compact form, close to the one used in publications. It means that Lagrangian terms can be written with summation over indices of broken symmetries and using special symbols for complicated expressions, such as covariant derivative and strength tensor for gauge fields. Tools for checking the correctness of the model, and for simplifying the output expressions are provided. The output is Feynman rules in terms of physical fields and independent parameters in the form of CompHEP model files, which allows one to start calculations of processes in the new physical model. Alternatively, Feynman rules can be generated in FeynArts format or as a LaTeX table. | ||

Running time:1sec (SM) - 8sec (MSSM) - 8min (MSSM with counterterms) |
