Abstract
An investigation of the hadronic final state in diffractive and non-di ffractive deep-inelastic electron-proton scattering at HERA is present ed, where diffractive data are selected experimentally by demanding a large gap in pseudo-rapidity around the proton remnant direction. The transverse energy flow in the hadronic final state is evaluated using a set of estimators which quantify topological properties. Using avail able Monte Carlo QCD calculations, it is demonstrated that the final s tate in diffractive DIS exhibits the features expected if the interact ion is interpreted as the scattering of an electron off a current quar k with associated effects of perturbative QCD. A model in which deep-i nelastic diffraction is taken to be the exchange of a pomeron with par tonic structure is found to reproduce the measurements well. Models fo r deep-inelastic ep scattering, in which a sizeable diffractive contri bution is present because of non-perturbative effects in the productio n of the hadronic final state, reproduce the general tendencies of the data but in all give a worse description.
