Q2-evolution of parton densities at small x values. Charm contribution in the combined H1 and ZEUS F2 data

Abstract

The Bessel-inspired behavior of parton densities at small x, obtained in the case of the flat initial conditions for DGLAP evolution equations, is used in the fixed flavor scheme to analyze precise H1+ZEUS combined data on the structure function F2.
