Self-Consistent Data Analysis of the Proton Structure Function G1 and Extraction of its Moments
Abstract
A reanalysis of all available world data on the longitudinal asymmetry A|| is presented. The proton structure function g1 was extracted within a unique framework of data inputs and assumptions. These data allowed for a reliable evaluation of moments of the structure function g1 in the Q2 range from 0.2 up to 30 GeV2. The Q2 evolution of the moments was studied in QCD by means of the Operator Product Expansion (OPE).
