Lessons from SUSY: ''Instead-of-Confinement'' Mechanism


I review physical scenarios in different vacua of N=2 supersymmetric QCD deformed by the mass term $\mu$ for the adjoint matter. This deformation breaks supersymmetry down to N=1 and at large $\mu$ the theory flows to N=1 QCD. I focus on dynamical scenarios which can serve as a prototypes of what we observe in the real world QCD In particular, I review the ''instead-of-confinement'' phase where quarks and gauge bosons screened at weak coupling evolve at strong coupling into monopole-antimonopole pairs confined by non-Abelian strings. I also discuss the relation of this picture to the Seiberg's duality.
