Rise of the DIS structure function F L at small x caused by double-logarithmic corrections

Abstract

Abstract We present calculation of F L in the double-logarithmic approximation (DLA) and demonstrate that the synergic effect of the factor 1/x from the α s 2 $$ {\alpha}_s^2 $$ -order and the steep x-dependence of the totally resummed double logarithmic contributions of higher orders ensures the power-like rise of F L at small x and arbitrary Q 2.
