Copyright policy )Analytical expression for the nonsinglet structure functions at smallxin the double logarithmic approximation
A simple analytic expression for the non-singlet structure function $f_{NS}$ is given. The expression is derived from the result of Ref. [1] obtained by low $x$ resummation of the quark ladder diagrams in the double logarithmic approximation of perturbative QCD.
