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 کاملThree-loop on-shell Feynman integrals with two masses
All three-loop on-shell QCD Feynman integrals with two masses can be reduced to 27 master integrals. Here we calculate these master integrals, expanded in ε, both exactly in the mass ratio and as series in limiting cases.
متن کاملEvaluation of two-loop self-energy diagram with three propagators.
Small momentum expansion of the ”sunset” diagram with three different masses is obtained. Coefficients at powers of p2 are evaluated explicitly in terms of dilogarithms and elementary functions. Also some power expansions of ”sunset” diagram in terms of different sets of variables are given. The ”sunset” diagram (see Fig. 1) was the object of investigation in several recent works [1, 2, 3, 4, 5...
متن کاملThree-loop vacuum integrals in FORM and REDUCE
The implementation of an algorithm for three-loop massive vacuum integrals, based on the explicit solution of the recurrence relations, in REDUCE and FORM is described.
متن کاملPercolation on a Feynman Diagram
In a recent paper [1] we investigated Potts models on “thin” random graphs – generic Feynman diagrams, using the idea that such models may be expressed as the N → 1 limit of a matrix model. The models displayed first order transitions for all q > 2, giving identical behaviour to the corresponding Bethe lattice. We use here one of the results of [1] namely a general saddle point solution for a q...
