Q2-evolution of parton densities at small x values. Combined H1 and ZEUS F2 data

Abstract

We use the Bessel-inspired behavior of the structure function F2 at small x, obtained for a flat initial condition in the DGLAP evolution equations, with "frozen" and analytic modifications of the strong coupling constant to study precise combined H1 and ZEUS data for the structure function F2 published recently.
