Abstract
The basic dynamic properties of two-particle bound states of “quarks” and “gluons” are investigated within a simple relativistic quantum field model with the Yukawa interaction. Provided with an analytic confinement of the constituent particles and small coupling constant, this model explains qualitatively the experimental evidence: the quarks and gluons are confined, the final bound states are stable, massless gluons constitute the glueballs and the Regge trajectories of “mesonic” orbital excitations are asymptotically linear.
