Seiberg duality

Seiberg duality

In quantum field theory, the Seiberg duality, discovered by Nathan Seiberg, is an S-duality relating two different supersymmetric QCDs in the low-energy (infrared) limit. This duality is only exact in the IR limit; in other words, the two theories are not identical, but their IR universality classes happen to match.

In particular, it relates an "N"=1 theory with SU(Nc) as the gauge group and Nf flavors of fundamental chiral multiplets and Nf flavors of antifundamental chiral multiplets in the chiral limit (no bare masses) with an N=1 chiral QCD with Nf-Nc colors and Nf flavors, where Nc and Nf are positive integers satisfying

:{1over 3}N_f < N_c < {2over 3}N_f .

Being an S-duality, it relates the strong coupling regime with the weak coupling regime, and interchanges chromoelectric fields with chromomagnetic fields, and chromoelectric charges with chromomagnetic monopoles. In particular, the Higgs phase is dual to the confinement phase as in the dual superconducting model.
