Dynamics of Strongly Bound Systems
Abstract
A dispersiontheoretic approach is developed for systems with large binding energies. Strong binding can be obtained if the oneparticle exchange force is singular at short distances. Manymeson exchange forces play an important role and are described by a suitable asymptotic expression. The method is used to construct a relativistic degenerate quark model of mesons. The model is unsatisfactory in the sense that, while yielding a sufficiently strong binding, the symmetry required for SU_{6}invariant vertices in the static limit is destroyed by the relativistic motion of the quarks. It is conjectured that a realistic quark model of mesons necessarily requires the existence of longrange, "superstrong" interactions.
