Abstract
We discuss what ingredients a realistic quark model must contain in order to provide a unified description of the observed low‐lying hadrons. The model then serves as our organization scheme to unify hadron‐hadron interactions at the quark level. It is pointed out specifically that two‐boson exchanges and other higher order effects can be incorporated without introduction of an additional ad hoc parameter. It is also stressed that, in baryon‐baryon interactions, the coupling to the 8×8 hidden‐color states is inevitable owing to one‐pion exchange together with quark interchange [as well as due to one‐gluon exchange and others]. The procedure, as adopted by Hwang, Macfarlane, and Walker at Indiana University, to express hadron‐hadron interactions in terms of elementary quark scattering amplitudes is outlined in some detail. We limit ourselves to discussion of general aspects and related uncertainties with some typical formulae shown for the purpose of illustration. A brief survey of the existing literature is also given.
