Abstract
A self-consistent dynamical mechanism is suggested which appears to be compatible with conventional ideas about relativistic field theory, and which prevents the appearance of the quanta of the field in outgoing or incoming scattering states. A model calculation is provided which illustrates the mechanism. The model produces a spectrum of conventional hadron states which corresponds to an infinitely rising Regge trajectory. All states are physical. When SU(3) internal quantum numbers are included, it is argued that the mechanism is stable only if the physical states have zero triality.
