Progress in Evaluating Some Complicated Types of Feynman Diagrams with Two (and More) Loops
A. I. Davydychev
Problems occurring in physically important non-trivial examples of loop calculations are discussed. A procedure of deriving expansions of two-loop self-energy diagrams with differe…

Some Exact Results for Two-Loop Diagrams with Three and Four External Lines
N. I. Ussyukina, A. I. Davydychev
Evaluation of three- and four-point diagrams with massless internal particles and arbitrary external momenta is considered. Exact results for some two-loop diagrams (planar and non…

Standard and hypergeometric representations for loop diagrams and the photon-photon scattering
A. I. Davydychev
By using the example of photon-photon scattering box diagrams, different representations for loop integrals are discussed. A connection between hypergeometric representation and di…
