✦ Synopsis

We report on some technical aspects of our calculation of α 4 s corrections to R(s) and the semi-leptonic τ decay width [1-3]. We discuss the inner structure of the result as well as the issue of its correctness. We demonstrate recently appeared independent evidence positively testing one of two components of our full result.

It is well known that in every experiment involving charged particles there are individual photons emitted with small energy ω and those with ω ≤ ω 0 will not be detected but are present in the data. The typical procedure to estimate this effect consists in taking the leading logarithm from the soft
