Compact analytical form for a class of three-loop vacuum Feynman diagrams
We present compact, fully analytical expressions for singular parts of a class of three-loop diagrams which cannot be factorized into lower-loop integrals. As a result of the calculations we obtain the analytical expression for the three-loop effective potential of the massive O(N) φ model presented recently by J.-M.Chung and B.K.Chung, Phys. Rev.D56, 6508 (1997). PACS numbers: 11.10.Gh Though ...

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.
