Results on inclusive single diffraction dissociation in π+ and K+p interactions at 250 GeV/c are presented for excited masses up to ≃9 GeV. Total and topological cross sections for meson and proton diffraction are determined and their energy dependence is studied. For meson diffraction, hadronization of the diffractive system is well described by a MC model with(Formula presented.)-Lund fragmentation and is found to be similar to hadronization in e+e−, annihilation in terms of thrust and mean charged multiplicity. Fireball-like decay models can be excluded from an elongation of the meson system along the beam-pomeron axis.
