摘要
We present an improved version of our program package oneloop which - written as a package for MAPLE (Char, Geddes, Gonnet, Leong, Monagan, Watt, MAPLE V Language and Library Reference Manuals) - 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(epsilon) parts relevant for two-loop calculations are now supported.
