Description of πp→Δ(1232)π and πp→Δ(1232)ρ(770) reaction proceeding via baryon exchange mechanism

1991

We analyze the available experimental data on the backward production processes πN→Δπ and πN→ Δπ in the framework of the strong-cut Reggeized absorption model, which is based on the exchange of the baryon Regge trajectoriesNα and Δδ with the associated cuts. The model describes rather well the data on the differential cross sections at incident π momenta ranging from 2.15 to 20 GeV/c. An essential contribution of Δδ exchange even at small energies (Elab of the order of a few GeV) is found. A model-independent analysis of data confirms this fenomena.

Inclusive production ofp-resonaces in πN-interactions

1991

A theoretical analysis of the inclusive production ofp-mesons in πN-collisions is carried out. It is shown that the reggeized pion exchange mechanism describes well a large set of the experimental data in the region of the Feynman variablex>0.6. The combination with the model of quark-gluon strings leads to a good agreement with the experiment for allx. The inclusive production of high spin resonances is discussed.
