Following arXiv:1310.2027 and arXiv:0801.0762, we consider a non-supersymmetric Seiberg duality between electric and magnetic %26quot;orientifold field theories%26quot;. These theories live on brane configurations of type 0%26apos; string theory. In the electric theory side the scalars acquire a mass and decouple, resulting in an SU(N-c) gauge theory coupled to N-f massless quarks and an additional massless fermion that transforms in the two-index antisymmetric representation. In the magnetic theory side there exists a fundamental meson field that develops a Coleman-Weinberg potential. At the one-loop approximation the potential admits a minimum with chiral symmetry breaking of the form SU(N-f)(L) x SU(N-f)(R) -%26gt; SU(N-f)(v) and an additional breaking of an axial U(1) symmetry. The resulting theory admits a spectrum whose massless degrees of freedom are N-f(2) Nambu-Goldstone bosons.
