Analytical evaluation of certain on-shell two-loop three-point diagrams
A. I. Davydychev, V. A. Smirnov
An analytical approach is applied to the calculation of some dimensionally-regulated two-loop vertex diagrams with essential on-shell singularities. Such diagrams are important for…
Three-body phase space: symmetrical treatments
A. I. Davydychev, R. Delbourgo
We derive expressions for three-body phase space that are explicitly symmetrical in the masses of the three particles, by three separate methods.
Geometrical approach to loop calculations and the epsilon-expansion of Feynman diagrams
A. I. Davydychev, M. Yu. Kalmykov
Some problems related to the structure of higher terms of the epsilon-expansion of Feynman diagrams are discussed.
Hadronic corrections to the muon decay
A. I. Davydychev, K. Schilcher, H. Spiesberger
We consider the O(alpha^2) hadronic corrections to the energy spectrum of the decay electron in muon decay. We find that the correction can be described, within good approximation,…
