摘要：A very wide body of HERA diffractive electroproduction data is confronted with the predictions
of the colour dipole model. In doing so we focus upon three different parameterisations of the
dipole scattering cross-section, whose parameters are xed by analysis of DIS structure function
data. This analysis strongly suggests the presence of saturation effects, but is not denitive because
the conclusion requires the inclusion of data at low-Q2 values. Having xed the parameters
of the models from the DIS structure function data, the resulting dipole cross sections can be used
to make genuine predictions for other reactions. Good agreement is obtained for all observables,
as is illustrated here for deeply virtual Compton scattering (DVCS) and diffractive deep inelastic
scattering (DDIS). There can be no doubting the success of the dipole scattering approach and
more precise observations are needed in order to expose its limitations
