چکیده
QCD analysis of the CCFR data for xF 3 and Higher–Twist Contribution. Abstract The QCD analysis of the xF 3 structure function measured in deep-inelastic scattering of neutrinos and antineutrinos on an iron target at the Fermilab Tevatron is done in 1–, 2– and 3–loop order of QCD. The x dependence of the higher–twist contribution is evaluated. The experimental value of higher–twist corrections to the Gross–Llewellyn Smith sum rule is discussed.

Next-to-next-to-leading order QCD analysis of combined data for xF 3 structure function and higher–twist contribution. Abstract The simultaneous QCD analysis of the xF 3 structure functions measured in deep-inelastic scattering by several collaborations is done up to 3–loop order of QCD. The x dependence of the higher–twist contribution is evaluated and turns out to be in a qualitative agreemen...

The improved next-to-next-to-leading order (NNLO) QCD analysis of the experimental data of the CCFR collaboration for the xF 3 structure function is made. Theoretical ambiguities of the NNLO ts are estimated by means of the Pad e resummation technique. The NNLO and the new N 3 LO s (Q 2) MS-matching conditions are used. In the process of the ts we are taking into account the the twist-4 1=Q 2-t...

Higher twists and α s (M Z) extractions from the NNLO QCD analysis of the CCFR data for the xF 3 structure function. Abstract A detailed next-to-next-to-leading order (NNLO) QCD analysis is performed for the experimental data of the CCFR collaboration for the xF 3 structure function. Theoretical ambiguities of the results of our NNLO fits are estimated by application of the Padé resummation tec...

The QCD analysis of the CCFR data for xF 3 : higher twists and α s (M Z) extractions at the NNLO and beyond Abstract The improved next-to-next-to-leading order (NNLO) QCD analysis of the experimental data of the CCFR collaboration for the xF 3 structure function is made. Theoretical ambiguities of the NNLO fits are estimated by means of the Padé re-summation technique, which was applied both in...
متن کاملB?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 ...
