Color Singlet Composite Superfields Containing Massless Composite Fermions Obtained by the 't Hooft Equation -- Supermetacolor. II

Abstract

Further study on supermetacolor, a supersymmetric extension of 't Hooft's metacolor, is made. In this scheme, both chiral symmetry and supersymmetry at the preon level are assumed to be taken over the composite level. As a consistency of this requirement, massless composite fermions should emerge and they should be members of chiral supermultiplets. In this paper, we develop a systematic prescription for finding superpartners of massless composite fermion. By making use of this method, superpartners of massless composite fermions are given explicitly in terms of original preon fields. In view of this result, it is argued that supermetacolor scheme is consistent one. At the same time this result leads to the suggestion that the above-mentioned symmetry realization (unbroken chiral symmetry and supersymmetry) is in fact possible.
