Manuscript Title: Calculation of long traces of gamma-matrices in the dimensional
regularization scheme. | ||

Authors: D. Graudenz | ||

Program title: DTRACE | ||

Catalogue identifier: ACBX_v1_0Distribution format: gz | ||

Journal reference: Comput. Phys. Commun. 69(1992)173 | ||

Programming language: C. | ||

Computer: MICROVAX. | ||

Operating system: UNIX. | ||

RAM: 3000K words | ||

Keywords: General purpose, Function, Dirac algebra, Gamma matrices, Symbolic calculation. | ||

Classification: 4.7. | ||

Nature of problem:The calculation of multi-particle cross section involves the calculation of long traces of Dirac matrices. Even symbolic manipulation programs are not capable of doing this because of the large number of terms. | ||

Running time:Depends on the length of the trace, 30 minutes for 16 matrices. |
