Issues in Large - Angle Scattering

We analyze phenomenologically several models for the high-energy scattering of hadrons through fixed, large angles. The emphasis is on trying to isolate and understand those aspects of hadronic forces which are important at large angles. We review the fixed-angle-lower bounds derived from analyticity and discuss how simple geometrical concepts can be used to guide our extrapolation of cross sections away from the forward and backward peaks into the large angle region. This extrapolation is important in understanding whether or not we need a new, hard component of the hadronic force to interpret the data. We try to isolate the important features of dual models, statistical models and constituent models and to clarify the possibility of experimental distinction between these approaches.
