Abstract
We use the method of a color effective Hamiltonian to study the properties of states in which a gluonic subsystem forms a color singlet, and we will s tudy the possibility that such a subsystem hadronizes as a separate unit. A parton system can normally be subdivided into singlet subsystems in many d ifferent ways, and one problem arises from the fact that the corresponding states are not orthogonal. We show that if only contributions of order 1/N- c(2) are included, the problem is greatly simplified. Only a very limited n umber of states are possible, and we present an orthogonalization procedure for these states. The result is simple and intuitive and could give an est imate of the possibility to produce color separated gluonic subsystems, if no dynamical effects are important, We also study with a simple Monte Carlo program the possibility that configurations which correspond to "short str ings" are dynamically favored. The advantage of our approach over more elab orate models is its simplicity, which makes it easier to estimate color rec onnection effects in reactions which are more complicated than the relative ly simple e(+)e(-) annihilation.
