SYSTEMATICS OF HADRON-PROTON DIFFRACTIVE SCATTERING AT HIGH-ENERGIES

We apply the eikonal formalism to existing π±, K±, p, {Mathematical expression}, ∑- and Ξ- elastic scattering data on a target proton in order to perform a detailed test of the additivity of eikonals of the constituent quark-quark interaction. The difference between the pion and kaon channels imposes an obvious flavor dependence. In addition, the systematic treatment of meson and baryon scattering for all values of t requires a renormalization of the fundamental interaction strength which persists in a rescattering treatment of the problem as well as with the inclusion of gluonic degrees of freedom. A variety of form factors and elementary amplitudes are studied with wide ranging consequences on the quality of the reproduction of the data. © 1990 Springer-Verlag.
