Hadron-hadron interaction in a string-flip model of quark confinement. I. Meson-meson interaction
The string-flip model of quark confinement is extended and applied to q/sup 2/q-bar /sup 2/ systems with color, spin, and flavor degrees of freedom. A realistic model for systems of two light mesons is constructed and the meson-meson interaction is investigated with the resonating-group method. Choosing the confinement strength for the confined (''hidden-color'') state is discussed in detail. We find that the interaction in the confined state often produces two-meson bound states or low-lying sharp resonances. The 2/sup +/ two-vector-meson systems and the K-K-bar interaction are studied in detail. The results are compared with those for other models and the possibility of observing ''hidden-color'' dominant resonances is discussed.
