title: Geometric scaling from Dokshitzer-Gribov-Lipatov-Altarelli-Parisi evolution.
abstract: We show that the geometric scaling of the total virtual photon-proton cross section data can be explained using standard linear Dokshitzer-Gribov-Altarelli-Parisi perturbative evolution with generic boundary conditions in a wide kinematic region. This allows us to single out the region where geometric scaling may provide evidence for parton saturation.
