Application of new multiloop QCD input to the analysis of xF 3 data
نویسنده
چکیده
The new theoretical input to the analysis of the experimental data of the CCFR collaboration for F3 structure function of νN deep inelastic scattering is considered. This input comes from the next-to-next-to-leading order corrections to the anomalous dimensions of the Mellin moments of the F3 structure function. The QCD scale Λ (4) MS is extracted from higher-twist independent fits. The results obtained demonstrate the minimization of the influence of perturbative QCD contributions to the value of Λ (4) MS .

QCD analysis of the CCFR data for xF 3 and Higher – Twist Contribution
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 ...

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...

QCD analysis of xF 3 structure function data and power correction to α s Abstract Power corrections both to the strong coupling constant and to the structure function itself are estimated on the basis of the LO, NLO and NNLO QCD analysis of xF 3 structure function data. The sign of correction to the coupling constant is found to be negative. The x-shape of a higher twist contribution to the str...

Wheat is a major agricultural crop in the Sistan region with a key role in local economy. The present study aimed to economically explore the efficiency of wheat production over the 2014-2016 period with the window data envelopment analysis (WDEA) approach. Also, the Malmquist productivity index was employed to assess the productivity of wheat growers in the study site under variable return to ...

One of the most serious principles in production theory in economic is the principle of "efficiency". Simply put, efficiency can be defined as the demand that the desired goals (outputs) are achieved with the minimum use of the available resources (inputs). In order to, distinguish the relative efficiency of organizational units with multiple inputs to produce multiple outputs, "Data Envelopmen...
