Diffractive Dijet Electroproduction at Hera H1 Collaboration

Abstract

The production of high transverse momentum jet pairs as components of the dissociating photon systemX in the diffractive deep-inelastic scattering process ep! eXY is studied, where the system Y is dominantly a proton and the squared four momentum transferred at the proton vertex is small. In a factorisable partonic pomeron model, the data suggest that the pomeron parton distributions are heavily dominated by gluons, with substantial contributions at all fractional momenta. The measured overall dijet rates and differential cross sections are generally well described by a model based on pomeron parton distributions determined from a QCD analysis of the diffractive structure function FD(3) 2 ( ;Q2; xIP ). This supports the hypothesis that universal pomeron parton densities can be used to describe different hard scattering processes in diffractive DIS. Viewed in terms of the diffractive scattering of partonic fluctuations of the photon, the data are dominated by photon Fock states of higher multiplicity than a simple q q pair.
