Direct extraction of QCD ΛMS from moments of structure functions in neutrino-nucleon scattering, using the CORGI approach
نویسنده
چکیده
We use recently calculated next-to-next-to-leading (NNLO) anomalous dimension coefficients for the n = 1, 3, 5, . . . , 13 moments of the xF3 structure function in νN scattering, together with the corresponding three-loop Wilson coefficients, to obtain improved QCD predictions for the moments. The Complete Renormalization Group Improvement (CORGI) approach is used, in which all dependence on renormalization or factorization scales is avoided by a complete resummation of ultraviolet logarithms. The Bernstein Polynomial method is used to compare these QCD predictions to the xF3 data

Improved analysis of moments of F3 in neutrino-nucleon scattering using the Bernstein polynomial method
We use recently calculated next-to-next-to-leading order (NNLO) anomalous dimension coefficients for the moments of the xF3 structure function in νN scattering, together with the corresponding three-loop Wilson coefficients, to obtain improved QCD predictions for both odd and even moments. To investigate the issue of renormalisation scheme dependence the Complete Renormalization Group Improveme...
متن کاملComplete Renormalization Group Improvement- Avoiding Factorization and Renormalization Scale Dependence in QCD Predictions
For moments of leptoproduction structure functions we show that all dependence on the renormalization and factorization scales disappears provided that all the ultraviolet logarithms involving the physical energy scale Q are completely resummed. The approach is closely related to Grunberg’s method of Effective Charges. A direct and simple method for extracting ΛMS from experimental data is advo...
متن کاملNuclear Effects in Neutrino Structure Functions
We discuss calculation of nuclear corrections to the structure functions for the deepinelastic scattering of muon and (anti)neutrino. Our approach includes a QCD description of the nucleon structure functions as well as the treatment of Fermi motion and nuclear binding, off-shell correction to bound nucleon structure functions, nuclear pion excess and nuclear shadowing. We emphasize the depende...
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 ...
متن کاملModeling Lepton-Nucleon Inelastic Scattering from High to Low Momentum Transfer
We present a model for inclusive charged lepton-nucleon and (anti)neutrino-nucleon cross sections at momentum transfer squared, Q2, ∼ 1 GeV2. We quantify the impact of existing low-Q charged-lepton deep-inelastic scattering (DIS) data on effects due to high-twist operators and on the extraction of parton distribution functions (PDFs). No evidence is found for twist-6 contributions to structure ...
