Abstract

The observed scaling laws for large angle exclusive hadronic reactions are successfully accounted for by the short-distance QCD quark interchange processes. We focus on three hadronic reactions which shows evidence for a slight oscillatory deviation from the expected scaling behaviour. Possible explanations for these oscillations and connections to spin observables will be mentioned. Better data from excisting facilities (or a possible future KEK proton accelerator, JHP) can clarify the theoretical situation.
