Spin-Dependent Structure Function g1 at Small x
B. I. Ermolaev, M. Greco, S. I. Troyan
Abstract
Accounting for double-logarithms of x and running QCD coupling leads to expressions for both the non-singlet and singlet components of g1. These expressions manifest the Regge asymptotics when x ->0 and differ considerably from the DGLAP expressions at small values of x.
