Description
A generalization of the non-Abelian version of the CPN-1 models (also known as Grassmannian models) is presented. The generalization helps accommodate a partial breaking of the non-Abelian gauge symmetry. Constituents of the composite gauge fields, in many cases, are naturally constrained to belong to an anomaly-free representation which in turn generates a composite scalar-simulating Higgs mechanism to break the gauge symmetry dynamically for large N. Two cases are studied in detail: one based on the SU(2) gauge group and the other on SO(10). Breakings such as SU(2)→U(1) or SO(10)→SU(5)xU(1) are found feasible. The properties of the composites fields and gauge boson masses are computed by doing a derivative expansion of the large N effective action
