Abstract: (APS)

For photon virtualities of

Q^{2} ≳ 20 {GeV}^{2}

, the results of the (hard Pomeron) fit in the tensor-Pomeron model in terms of the variables,

Q^{2}

, and the virtual-photon-proton energy squared,

W^{2}

, provide empirical evidence for the validity of the color dipole picture (CDP). Consistency of the CDP with the perturbative QCD (pQCD) improved parton model implies the prediction of

C_{2} = ε_{0} ≅ 0.30

for the exponent

C_{2}

of the energy-squared dependence in agreement with the results of the fits. For

Q^{2} ≲ 20 G {eV}^{2}

, the CDP yields a parameter-free smooth transition from

Q^{2} ≳ 20 {GeV}^{2}

to

Q^{2} = 0

photoproduction, in distinction from the tensor-Pomeron model that relies on the additional parameter quantifying the intercept of the soft-Pomeron trajectory.
