- This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract We present a new program performing the sector decomposition and integrating the expression afterwards. The program takes a set of propagators and a set of indices as input and returns the epsilon-expansion of the corresponding integral. Title of program: FIESTA Catalogue Id: AECP_v1_0 Nature of problem The sector decomposition approach to evaluating Feynman integrals falls apart into the sector decomposition itself, where one has to minimize the number of sectors; the pole resolution and epsilon expansion; and the numerical integration of the resulting expression.
