- Abstract It is shown how all one-loop integrals arising from Feynman diagrams in a general gauge theory can be reduced to scalar integrals. The scheme presented here successfully treats the case when the momenta are linear dependent. A set of algebraic manipulation routines written in REDUCE and that implements the scheme is described. Title of program: LERG-I Catalogue Id: ABBX_v1_0 Nature of problem Expressions obtained in the calculation of one-loop radiative corrections to processes in high energy physics are generally simplified by expressing them in terms of scalar integrals. LERG-I makes the reduction from form factors corresponding to the various possible Lorentz tensors occuring in the problem.
