Hadron diffraction dissociation in the additive quark model

Diffraction dissociation of hadrons is considered in the impulse approximation of the additive quark model. An account for a possible excitation of constituent quarks enables one to descrihe the diffraction dissociation cross sections at low momentum transfers. The calculated integrated cross sections and slopes of the inelastic diffraction cones are in agreement with the experimental data. Relations between the cross sections of various diffractive processes are obtained. The double diffraction dissociation processes are discussed. Using the Pumplin condition one gets restrictions on the radius of the quark-quark interaction
