oneloop 2.0 -- A Program Package calculating One-Loop Integrals

Abstract

We present an improved version of our program package oneloop which -- written as a package for MAPLE -- solves one-loop Feynman integrals. The package is calculating one-, two- and three-point functions both algebraically and numerically to any tensor rank. In addition to the original version oneloop 2.0 also calculates infrared divergent integrals. Higher powers of propagator terms and the $O(\text{eps})$ parts relevant for two-loop calculations are now supported.
