We report on a successful attempt to extract the cross-section for the high-energy scattering of colour dipoles of fixed transverse size off protons using electroproduction and photoproduction total cross-section data, subject to the constraint provided by the ratio of the overall photon dissociation cross-section to the total cross-section. 
The total virtual photoabsorption cross section, deeply virtual Compton scattering and vector-meson production
Abstract.Based on the generic two-gluon-exchange dynamical mechanism for deeply inelastic scattering at low $x \simeq Q^2/W^2 \ll 1$, we stress the intimate direct connection between the total
Erratum to The total virtual photoabsorption cross section, deeply virtual Compton scattering and vector-meson production
Based on the generic two-gluon-exchange dynamical mechanism for deeply inelastic scattering at low $x \simeq Q^2/W^2 \ll 1$ , we stress the intimate direct connection between the total virtual
Gluon saturation in the colour dipole model
We use data on the deep inelastic structure function F2 in order to constrain the cross-section for scattering a colour dipole off a proton. The data seem to prefer parameterisations which include
The colour dipole approach to small-x processes
We explain why it is possible to formulate a wide variety of high-energy (small-x) photon-proton processes in terms of a universal dipole cross section and compare and contrast various
High energy photoproduction
The experimental and phenomenological status of high energy photoproduction is reviewed. Topics covered include the structure of the photon, production of jets, heavy flavours and prompt photons,
Further success of the colour dipole model
We confront a very wide body of HERA diffractive electroproduction data with the predictions of the colour dipole model. We focus upon three different parameterisations of the dipole scattering
Nuclear heavy quark photoproduction in a saturation model
Abstract.We calculate the nuclear inclusive and diffractive cross sections for heavy quark photoproduction within a phenomenological saturation approach. The nuclear cross section is obtained by the
On the energy dependence of the dipole-proton cross section in deep inelastic scattering
We study the dipole picture of high-energy virtual-photon-proton scattering. It is shown that different choices for the energy variable in the dipole cross section used in the literature are not

We determine the diffractive scattering amplitude of a color-dipole on a nucleon using a non-perturbative model of QCD which contains only parameters taken from low-energy physics. This allows to
Phenomenological description of the γ ⋆ p cross section at low Q 2
Low Q2 photon-proton cross sections are analysed using a simple, QCD-motivated parametrisation $\sigma_{\gamma^\star p}\propto 1/(Q^2+Q_0^2)$, which gives a good description of the data. The Q2
Saturation effects in deep inelastic scattering at low Q**2 and its implications on diffraction
We present a model based on the concept of saturation for small $Q^2$ and small $x$. With only three parameters we achieve a good description of all Deep Inelastic Scattering data below $x=0.01$.
Measurements of the Photon Total Cross Section on Protons from 18 to 185 GeV
The photon total cross section on protons has been measured with high precision in the Fermilab tagged-photon beam for photon energies from 18 to 185 GeV. The cross section decreases to a broad

A fit is made to the data for the proton structure function up toQ2=10 GeV2, including the real γp total cross-section. It is economical and simple, and its form is motivated by physical principles.
