Geometrical approach to Feynman integrals and the epsilon-expansion
Abstract
Description
Application of the geometrically-inspired representations to the epsilon-expansion of the two-point function with different masses is considered. Explicit result for an arbitrary term of the expansion is obtained in terms of log-sine integrals. Construction of the epsilon-expansion in the three-point case is also discussed.
