EXOTIC NONSUPERSYMMETRIC GAUGE DYNAMICS FROM SUPERSYMMETRIC QCD

we extend Seiberg's qualitative picture cf the behavior of supersymmet ric QCD to nonsupersymmetric models by adding soft supersymmetry-break ing terms. In this way we recover the standard vacuum of QCD with N-f flavors and N-c colors when N-f < N-c. However, for N-f greater than o r equal to N-c, we find new exotic states-new vacua with spontaneously broken baryon number for N-f = N-c, and a vacuum state with unbroken chiral symmetry for N-f > N-c. These exotic vacua contain massless com posite fermions and, in some cases, dynamically generated gauge bosons . In particular Seiberg's electric-magnetic duality seems to persist a lso in the presence of (small) soft supersymmetry breaking. We argue t hat certain, specially tailored, lattice simulations may be able to de tect the novel phenomena. Most of the exotic behavior does not survive the decoupling Limit of large SUSY-breaking parameters.
