Hadronization effects in inclusive tau decay

TL;DR

This paper examines how nonperturbative hadronization effects significantly influence low-energy strong interactions, especially constraining the Adler function and affecting the analysis of inclusive tau decay.

Contribution

It highlights the importance of hadronization effects in low-energy QCD processes and their impact on tau decay analysis.

Findings

Hadronization effects impose constraints on the Adler function.

Nonperturbative effects are crucial in low-energy tau decay.

Theoretical analysis must account for hadronization effects.

Abstract

It is shown that the nonperturbative effects due to hadronization play a crucial role in low-energy strong interaction processes. Specifically, such effects impose a stringent constraint on the infrared behavior of the Adler function and play an essential role in the theoretical analysis of inclusive tau lepton decay.
