Proton spin structure at small-x

Year: 2019

Type: article

Abstract: We generalize the Bartels-Ermolaev-Ryskin approach for the g1 structure function at small-x [1], [2] to determine the small-x asymptotic behavior of the orbital angular momentum distributions in QCD. We present an exact analytical solution of the evolution equation in the double logarithmic approximation and discuss its implications for the proton spin problem.
