Abstract We describe the program DTRACE that is capable of calculating products of traces of γ-matrices in d dimensions. DTRACE gives the result in a form suitable as input for algebraic manipulation programs. Title of program: DTRACE Catalogue Id: ACBX_v1_0 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. Versions of this program held in the CPC repository in Mendeley Data ACBX_v1_0; DTRACE; 10.1016/0010-4655(92)90137-N This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
