Feynman Integral Evaluation by a Sector decomposiTion Approach (FIESTA)

Understand

Up to the moment there are two known algorithms of sector decomposition: an original private algorithm of Binoth and Heinrich and an algorithm made public lastyear by Bogner and Weinzierl.

• 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.
