Аннотация:We consider an algorithm for constructing the power series (in the external momentum) of two-loop two-point diagrams with arbitrary masses of the internal particles. Comparison with a numerical calculation of some two-loop diagrams occurring in the Standard Model shows that the first few terms of the expansion provide good approximations in the region when the external momentum is below the threshold.
