SU(6) classification for ''in'' and ''out'' states

Within the context of the quark model with interaction, SU(6) algebras classifying ''in'' and ''out'' states are constructed and the unitary transformation relating these algebras to the SU(6)/sub W ,/ algebra generated by integrals of local currents is given simply. The formulation is general so that one may study kinematic effects, which arise even in the absence of interaction from the angular requirements on the generators of the classification algebras, separate from dynamical effects, which are peculiar to the nature of the interaction and are also induced by these angular constraints
