On two-particle N=1 supersymmetric composite unified models

A class of two-particle N=1 supersymmetric composite unified models satisfying the anomaly matching and a cancellation conditions, decoupling condition, and survival hypothesis is considered. A unique admissible set of the light states containing the spectator states on a par with the composite ones is found. It is shown that at low mass scales this set contains exactly four families of opdinary fermions without any additional exotics. The N=1 supersymmetric unified model [SU(6)]2 (or [SU(8)]2) with a fixed set of four second-rank tensors as matter fields is suggested as the unified model for description of composite lepton and quark interactions
