Abstract

Concise and practical formulas for Feynman-parametric integrals are assembled and presented in the form of Feynman-Dyson rules in parametric space. These rules enable us to write down S-matrix elements directly in terms of some parametric functions. They are particularly useful for construction of ultraviolet- and infrared-divergence-free Feynman-parametric integrals in a form suitable for numerical integration.
