摘要：
We propose the SUSY SU(7) unification of the SU(3)(C) x SU(4)(W) x U(1)(B-L) model. Such unification scenario has rich symmetry breaking chains in a five-dimensional orbifold. We study in detail the SUSY SU(7) symmetry breaking into SU(3)(C) x SU(4)(W) x U(1)(B-L) by boundary conditions in a Randall- Sundrum background and its AdS/CFT interpretation. We find that successful gauge coupling unification can be achieved in our scenario. Gauge unification favors low left-right and unification scales with tree-level sin(2) theta(W) = 0.15. We use the AdS/CFT dual of the conformal supersymmetry breaking scenario to break the remaining N = 1 supersymmetry. We employ AdS/CFT to reproduce the NSVZ formula and obtain the structure of the Seiberg duality in the strong coupling region for 3/2 N-c < N-F < 3N(C). We show that supersymmetry is indeed broken in the conformal supersymmetry breaking scenario with a vanishing singlet vacuum expectation value.
