A next-to-leading-order QCD analysis of data on diffractive
deep inelastic scattering from the ZEUS experiment

                 ZEUS Collaboration

ZEUS inclusive diffractive cross-sections data were used in a DGLAP 
next-to-leading-order QCD analysis to extract the diffractive parton 
distribution functions. Data on diffractive dijet production in deep
inelastic scattering were also included in the fit to constrain the gluon 
density. Diffractive photoproduction dijet were used to test the extracted 
parton densities.
