Abstract
Including the new HERA data, the gamma *p total cross-section is analyzed in the generalized vector dominance/color-dipole picture (GVD/CDP) that contains scaling in eta = (Q(2) + m(0)(2))/Lambda (2)(W-2), where Lambda (2)(W-2) is an increasing function of W-2. At any Q(2), for W-2 --> infinity, the cross-sections for virtual and real photons become identical, sigma (gamma *p)(W-2, Q(2))/(sigma gammap)(W-2) --> 1. The gluon density deduced from the color-dipole cross-section fulfills the leading order DGLAP relationship. Evolution a la DGLAP breaks down for n less than or similar to 0.1.
