Resumen
WE PROPOSE A NEW SET OF MASTER INTEGRALS WHICH CAN BE USED AS A BASIS FOR CERTAIN MULTILOOP CALCULATIONS IN MASSLESS GAUGE FIELD THEORIES. IN THESE THEORIES WE CONSIDER THREE-POINT FEYNMAN DIAGRAMS WITH ARBITRARY NUMBER OF LOOPS. THE CORRESPONDING MULTILOOP INTEGRALS MAY BE DECOMPOSED IN TERMS OF THIS SET OF THE MASTER INTEGRALS. WE CONSTRUCT A NEW REDUCTION PROCEDURE WHICH WE APPLY TO PERFORM THIS DECOMPOSITION.
