HyperFORM: a FORM package for parametric integration with hyperlogarithms

Abstract We present an implementation of algorithms for the symbolic integration of hyperlogarithms multiplied by rational functions in the computer algebra system . This implementation encompasses cases where hyperlogarithms have rational letters or a rational argument. It complements the previous implementation, , in by Erik Panzer, utilizing the advantages of in the efficient handling of large symbolic expressions. Among a wide range of applications, this approach enables the computation of many Feynman integrals.
