The Gross–Llewellyn Smith Sum Rule in the Analytic Approach to Perturbative QCD
We apply analytic perturbation theory to the Gross–Llewellyn Smith sum rule. We study the Q2 evolution and the renormalization scheme dependence of the analytic three-loop QCD correction to this sum rule, and demonstrate that the results are practically renormalization scheme independent and lead to rather different Q2 evolution than the standard perturbative correction possesses. PACS: 11.10.H...
متن کاملDeficiency of the Gross - Llewellyn Smith Sum Rule and Qcd Vacuum Polarization Effect
From the analysis of the recent CCFR Collaboration data for the structure function xF3(x,Q ) (0.015 < x < 0.65 and 1.2 GeV 2 < |Q| < 501 GeV ) of the deep inelastic neutrino nucleon scattering we conclude that probably part of the nucleon baryon number is due to the vacuum polarization effects. The deep inelastic lepton nucleon scattering processes (DIS) occurring at small distances characteriz...
متن کاملQuark Mass Corrections to the Bjorken and Gross–Llewellyn-Smith Sum Rules
Quark mass corrections to the spin partonic structure function g1(x,Q 2) and function F3(x,Q 2) are obtained at the order O(αs) along with the coefficient functions C(A) and C(V ) related to the Bjorken and Gross–Llewellyn-Smith sum rules. In the massless limit the difference between F3 and g1 is encountered to be (αs/π)CF (1− x). The results for the functions C(A) and C(V ) at m = 0 agree with...
متن کاملNNLO QCD Analysis of CCFR data on xF3 Structure Function and Gross-Llewellyn Smith Sum Rule with Higher Twist and Nuclear Corrections
A detailed NNLO QCD analysis of new CCFR data on the xF3 structure function including the target mass, higher twist and nuclear corrections was performed and parametrizations of the perturbative and power terms of the structure function were constructed. The results of QCD analysis of the structure function were used to study the Q2−dependence of the Gross-Llewellyn Smith sum rule. The αS/π−exp...
متن کاملEllis-Jaffe sum rule: The estimates of the next-to-next-to-leading-order QCD corrections.
The procedure of the estimates of the higher-order perturbative QCD corrections to the physical quantities is generalized to the case when the quantities under consideration obey the renormalization group equations with the corresponding anomalous dimension functions. This procedure is used to estimate the α s-corrections to the singlet part of the Ellis-Jaffe sum rule for f = 3 numbers of flav...
