On the low-energy behavior of the Adler function

Abstract

The infrared behavior of the Adler function is examined by making use of a recently derived integral representation for the latter. The obtained result for the Adler function agrees with its experimental prediction in the entire energy range. The inclusive $\tau$ lepton decay is studied in the framework of the developed approach.
