RationalizeRoots: Software Package for the Rationalization of Square Roots

Understand

The computation of Feynman integrals often involves square roots.

• One way to obtain a solution in terms of multiple polylogarithms is to rationalize these square roots by a suitable variable change.
• We present a program that can be used to find such transformations.
• After an introduction to the theoretical background, we explain in detail how to use the program in practice.
