چکیده

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 τ lepton width resulting from such a technique are discussed.

Renormalization group analysis of the τ-lepton decay within QCD

A technique to sum up the regular corrections appearing under the analytic continuation from the spacelike momentum region to the timelike one is proposed. A perturbative part of the inclusive semileptonic decay width of the τ -lepton in analyzed in detail. At present the theory of electroweak interactions is tested with truly great accuracy due to creation of the modern experimental machines [...

Small-Size Instanton Corrections to the τ Hadronic Width

We compute the effect of small-size instanton corrections to current-current correlators, for all combinations of axial, vector, and possibly flavour nondiagonal currents. We apply our result to the hadronic decays of the τ lepton, in order to assess the reliability of the determination of αS from the τ hadronic width.

Instanton–anti-instanton pair induced contributions to Re+e−→hadrons and Rτ→hadrons

The instanton–anti-instanton pair induced asymptotics of perturbation theory expansion for the cross section of electron–positron pair annihilation to hadrons and hadronic width of τ -lepton was found. For Nf = Nc the nonperturbative instanton contribution is finite and may be calculated without phenomenological input. The instanton induced peturbative asymptotics was shown to be enhanced as (n...

Charged Scalar Particles and Τ Leptonic Decay

Charged scalar particles introduced in some extensions of the standard model can induce τ leptonic decay at tree level. We find that with some charged SU(2)-singlet scalar particles, like ones introduced in Zee-type models, τ leptonic decay width is always smaller than what is predicted by the standard model, therefore they may offer a natural solution to τ decay puzzle. To be more specific, we...

We describe some ways how higher order corrections can reveal themselves if integrated over the infrared region. We show that in different renormalization group (RG) schemes and for some observables one has no factorial divergences. We argue that for treating things in the infrared region it is preferable to start with a RG scheme without the infrared Landau pole in the running coupling constan...
