标题： Infrared modified analysis for the $τ$ lepton width

摘要： TO_BE_TRANSLATED: We argue that accounting for higher order corrections in QCD by integrating a running coupling constant through an infrared region can be most easily done with making use of a scheme without the Landau pole. Within this approach the entire ambiguity of the answer is identical to that of the choice of renormalization scheme. The uncertainties for the $\tau$ lepton width resulting from such a technique are discussed. 显示英文摘要

摘要： We argue that accounting for higher order corrections in QCD by integrating a running coupling constant through an infrared region can be most easily done with making use of a scheme without the Landau pole. Within this approach the entire ambiguity of the answer is identical to that of the choice of renormalization scheme. The uncertainties for the $\tau$ lepton width resulting from such a technique are discussed.
