Hadronic effects in low-energy QCD: inclusive tau lepton decay

Abstract

The inclusive tau lepton hadronic decay is studied within Dispersive approach to QCD. The significance of effects due to hadronization is convincingly demonstrated. The approach on hand proves to be capable of describing experimental data on tau lepton hadronic decay in vector and axial-vector channels. The vicinity of values of QCD scale parameter obtained in both channels bears witness to the self-consistency of developed approach.
