The regional strategy in the asymptotic expansion of two-loop vertex Feynman diagrams
V. A. Smirnov, E. R. Rakhmetov M. V. Lomonosov Moscow State University
Abstract:
General prescriptions for evaluating coefficients at arbitrary powers and logarithms in the asymptotic expansion of Feynman diagrams in the Sudakov limit are discussed and illustrated with two-loop examples. Peculiarities connected with the evaluation of individual terms in the expansion, in particular, the introduction of an auxiliary analytic regularization, are characterized.
