Wide Angle Behavior of a Double Scattering Diagram

Landshoff has recently pointed out that in composite models for hadronhadron wide angle scattering, processes where the constituents remain close to their mass shells throughout the scattering can dominate the wide angle cross sections. We use a Feynman parametric integral to estimate the phase space for such a process and confirm Landshoff’s result. The differential cross section for elastic r-x kattering at fixed c. m. angle is found to fall off as S-5 , rather than as s -6 which is predicted by the dimensional counting rules.
