Color dipole cross-section from unifying the color-dipole picture and improved saturation models
Year: 2024
Type: article
Abstract: We present an analysis of the color-dipole picture for determination of the gluon density at low-x which is obtained from the Altarelli-Martinelli equation by expansion at distinct points of expansion. The dipole cross-sections with respect to the improved saturation model of Bartels–Golec-Biernat–Kowalski are obtained in a wide range of transverse sizes r and compared with the Golec-Biernat-W u ̈ sthoff model. We find that the model gives a good description of the dipole cross-section at large r which confirms saturation and matches the perturbative QCD result at a small r due to the significant role of the running of the gluon distribution.
