Feynman diagrams as a weight system : four - loop test of a four - term relation ∗ )
At four loops there first occurs a test of the four-term relation derived by the second author in the course of investigating whether counterterms from subdivergencefree diagrams form a weight system. This test relates counterterms in a four-dimensional field theory with Yukawa and φ interactions, where no such relation was previously suspected. Using integration by parts, we reduce each counte...
متن کاملFour-dimensional integration by parts with differential renormalization as a method of evaluation of Feynman diagrams
It is shown how strictly four-dimensional integration by parts combined with differential renormalization and its infrared analogue can be applied for calculation of Feynman diagrams. submitted to Teor. Mat. Fiz. E-mail: [email protected] 1. Integration by parts (IBP) [1] within dimensional regularization [2] turned out to be one of the most powerful methods of calculation of Feynman di...
متن کاملWeight Systems from Feynman Diagrams
We find that the overall UV divergences of a renormalizable field theory with trivalent vertices fulfil a four-term relation. They thus come close to establish a weight system. This provides a first explanation of the recent successful association of renormalization theory with knot theory.
متن کاملAlgorithmic Calculation of Two-loop Feynman Diagrams *
In a recent paper [1] a new powerful method to calculate Feynman diagrams was proposed. It consists in setting up a Taylor series expansion in the external momenta squared. The Taylor coefficients are obtained from the original diagram by differentiation and putting the external momenta equal to zero. It was demonstrated that by a certain conformal mapping and subsequent resummation by means of...
متن کاملString derivation of two-loop Feynman diagrams∗
We briefly review the technology involved in extracting the field– theory limit of multiloop bosonic string amplitudes, and we apply it to the evaluation of simple two-loop diagrams involving scalars and gauge bosons.
