Abstract Fragmentation measurements are presented for diffractive deep inelastic ep scattering data in the Breit frame of reference. The evolution of the peak and width of the current hemisphere fragmentation functions and of the slope of the transverse momentum spectrum for charged particles is studied as a function of photon virtuality, Q, and is found to agree with results obtained in non-diffractive deep inelastic scattering. The data are interpreted in a picture where the diffractive final state originates from either a q q bar or a q q bar g partonic configuration.
