A CHIRAL SU(N) GAUGE-THEORY AND ITS NONCHIRAL SPIN(8) DUAL

We study supersymmetric SU(N - 4) gauge theories with a symmetric tens or and N antifundamental representations. The theory with W = 0 has a dual description in terms of a non-chiral Spin(8) theory with one spin or and N vectors. This duality flows to the SO(N) duality of Seiberg a nd to a duality proposed by one of us. It also flows to dualities for a number of Spin(m) theories, m less than or equal to 8. For N = 6, wh en an N = 2 SUSY superpotential is added, the singularities of Seiberg and Witten are recovered. For N less than or equal to 6, a mass for t he spinor generates the branches of SO(8) theories found by Intriligat or and Seiberg. Other phenomena include a classical constraint mapped to an anomaly equation under duality and an intricate consistency chec k on the renormalization group flow.
