abstract

• A simple analytic expression for the nonsinglet structure function ${f}_{\mathrm{NS}}$ is given. The expression is derived from the result of Ermolaev, Manaenkov, and Ryskin obtained by low x resummation of the quark ladder diagrams in the double logarithmic approximation of perturbative QCD.
