DGLAP improved saturation model with heavy flavours

Abstract

The DGLAP improved saturation model of Bartels, Golec and Kowalski is supplemented by the contribution from the heavy quarks: charm and beauty. It is shown to give good description of both the total proton structure function F2 and, as a prediction, the heavy quarks contribution F2c and F2b. The reasonable agreement for the longitudinal and diffractive structure functions is also found.
