Loops: Procedures for multiloop calculations in quantum field theory for the reduce system

Abstract We present a REDUCE package for analitical computation of arbitrary massless, one- and two-loop Feynman diagrams of the propagator type within dimensional regularization. The package calculates Laurent expansions of diagrams in the parameter of dimensional regularization. Title of program: LOOPS Catalogue Id: ABJO_v1_0 Nature of problem Dimensionally regularized multiloop massless Feynman integrals of a propagator type (so called p-integrals), usually appearing in the tasks of the quantum field theory, in particular, high energy physics calculations are computed analytically here. Versions of this program held in the CPC repository in Mendeley Data ABJO_v1_0; LOOPS; 10.1016/0010-4655(89)90077-5 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
