چکیده

We present a brief (mainly bibliographical) report on recently performed calculations of terms of order O(α 4 s n 2 f) and O(α 4 s n 2 f m 2 q) for hadronic Z and τ decay rates. A few details about the analytical evaluation of the masters integrals appearing in the course of calculations are presented.

The role of electroweak penguin and magnetic dipole QCD penguin on hadronic b Quark Decays

This research, works with the effective Hamiltonian and the quark model. Using, the decay rates of matter-antimatter of b quark was investigated. We described the effective Hamiltonian theory which was applied to the calculation of current-current (Q1,2), QCD penguin (Q3,…,6), magnetic dipole (Q8) and electroweak penguin (Q7,…,10) decay rates. The gluonic penguin structure of hadronic decays ...

QCD Analysis of Hadronic τ Decays Revisited

The calculation of perturbative corrections to the spectral moments observable in hadronic τ decays is reconsidered. The exact order-αs results and the resummation procedure of Le Diberder and Pich are compared with a partial resummation of the perturbative series based on the analysis of so-called renormalon chains. The perturbative analysis is complemented by a model-independent description o...

QCD Tests from Tau Decays

The total τ hadronic width can be accurately calculated using analyticity and the operator product expansion. The theoretical analysis of this observable is updated to include all available perturbative and non-perturbative corrections. The experimental determination of αs(M 2 τ) and its actual uncertainties are discussed.

B?J/?(?,K) Decays within QCD Factorization Approach

We used QCD factorization for the hadronic matrix elements to show that the existing data, in particular the branching ratios BR ( ?J/?K) and BR ( ?J/??), can be accounted for this approach. We analyzed the decay within the framework of QCD factorization. We have complete calculation of the relevant hard-scattering kernels for twist-2 and twist-3. We calculated this decays in a special scale ...

ALEPH Tau Spectral Functions and QCD

Hadronic τ decays provide a clean laboratory for the precise study of quantum chromodynamics (QCD). Observables based on the spectral functions of hadronic τ decays can be related to QCD quark-level calculations to determine fundamental quantities like the strong coupling constant, quark and gluon condensates. Using the ALEPH spectral functions and branching ratios, complemented by some other a...
