The effects due to hadronization in the inclusive tau lepton decay

The hadronic decay of tau lepton provides an excellent opportunity to test the nonperturbative aspects of Quantum Chromodynamics and furnishes stringent constraints on possible New Physics beyond the Standard Model.

Theoretical description of inclusive tau lepton hadronic decay is performed in the framework of Dispersive approach to QCD.

The significance of effects due to hadronization is demonstrated. The developed approach provides nearly identical values of QCD scale parameter in vector and axial-vector channels.
