Rescattering by a nucleus of (Nπ) and (3π) beams after their coherent formation
Verebryusov V. S., Ponomarev L. A.
The coherent processes of diffractive dissociation ΝΑ^(Νπ]Λ and πΑ-+{ϊπ)Α are analyzed within the framework of the Drell-Hiida-Deck model, which was modified by taking into account the rescattering effects. It is shown that the scattering cross section of a (Νπ) beam has a "normal" value, whereas the scattering cross section of a (3π) beam is anomalously small. The small cross section is attributable to the small pomeron vertex function of the ρ mesons.
