What Can We Learn From Polarized Structure Function Data?
Richard D. Ball, Giovanni Ridolfi, Guido Altarelli, Stefano Forte
Abstract
We summarise the perturbative QCD analysis of the structure function data for g1 from longitudinally polarized deep inelastic scattering from proton, deuteron and neutron targets, with particular emphasis on testing sum rules, determining helicity fractions, and extracting the strong coupling from both scaling violations and the Bjorken sum rule.
