The energy dependence of the saturation scale in DIS at low x

AbstractConsistency of the previously suggested color-dipole representation of deep-inelastic scattering (DIS) and vector-meson production at low x with DGLAP evolution allows one to predict the exponent of the W2 dependence of the saturation scale, Λsat2(W2)∼(W2)C2. One finds C2theory=0.27 in agreement with the model-independent analysis of the experimental data from HERA on deep-inelastic electron scattering
