SLAC-PUB-864 March 1971 PHYSICAL BASIS FOR AN EXPANDING HIGH-ENERGY INTERACTION RADIUS”

A simple argument concerning bremsstrahlung shows how the presence of many %ofV particles increases the radius of a system. This suggests there is a natural basis for a growth of a particle’s effective radius at high energy in terms of the angular momentum fluctuations of a system containing increasingly larger numbers of particles. A formula which results for the radius in terms of the multiplicity, R = fi, appears to be compatible with experiment with a reasonable value for the parameter . (Submitted to Phys. Rev.
