Asymptotic Expansions of Two-Loop Feynman Diagrams in the Sudakov Limit
Recently presented explicit formulae for asymptotic expansions of Feynman diagrams in the Sudakov limit [1] are applied to typical two-loop diagrams. For a diagram with one non-zero mass these formulae provide an algorithm for analytical calculation of all powers and logarithms, i.e. coefficients in the corresponding expansion (Q) ∑ n,j=0 cnjt −n ln t, with t = Q/m and j ≤ 4. Results for the co...
متن کاملAutomatic application of successive asymptotic expansions of Feynman diagrams
We discuss the program EXP used to automate the successive application of asymptotic expansions to Feynman diagrams. We focus on the generation of the relevant subgraphs and the determination of the topologies for the remaining integrals. Both tasks can be solved by using backtracking-type recursive algorithms. In addition, an application of EXP is presented, where the integrals were calculated...
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.
متن کاملThe two-loop vector form factor in the Sudakov limit
Recently two-loop electroweak corrections to the neutral current four-fermion processes at high energies have been presented. The basic ingredient of this calculation is the evaluation of the two-loop corrections to the Abelian vector form factor in a spontaneously broken SU(2) gauge model. Whereas the final result and the derivation of the four-fermion cross sections from evolution equations h...
