Abstract
A phenomenological study of the final combined HERA data on inclusive deep inelastic scattering has been performed. The data are presented and investigated for a kinematic range extending from values of the four-momentum transfer, Q 2 , above 1 0 4 GeV 2 down to the lowest values observable at HERA of Q 2 = 0.045 GeV 2 and Bjorken x , x Bj = 6 × 10 − 7 . The data are well described by fits based on perturbative quantum chromodynamics (QCD) using collinear factorisation and evolution of the parton densities encompassed in the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi formalism from the highest Q 2 down to Q 2 of a few GeV 2 . The Regge formalism with the soft Pomeron pole can describe the data up to Q 2 ≈ 0.65 GeV 2 . The complete data set can be described by a new fit using the Abramowicz-Levin-Levy-Maor parametrization. The region between the Regge and the perturbative QCD regimes is of particular interest.
