RELATIVISTIC BOUND-STATES IN QCD

This paper deals with the construction of a nonlocal theory of hadrons as bound states of quarks and gluons. The starting point of the investigation is a relativistic covariant definition of instantaneous bound states and the supposition of the dominance of an instantaneous gluon interaction. We have generalized the unified description of the nonlocal relativistic heavy and light mesons to the case of many-quark and many-gluon configurations using an operator approach. This includes the rules for the construction of relativistic wave functions in an arbitrary frame.
