Idea

Seiberg duality (named after (Seiberg)) is a version of electric-magnetic duality in supersymmetric gauge theory.

For supersymmetric QCD it identifies in the infrared (long distance limit, and only there) the quarks and gluons in a theory with N fN_f quark flavors and SU(N c)SU(N_c) gauge group for

N f>N c+1 N_f \gt N_c +1

with solitons in a theory of N fN_f quark flavors and gauge group SU(N˜ c)SU(\tilde N_c), where

N˜ c=N fN c. \tilde N_c = N_f - N_c \,.

Properties

Realization in string theory

Seiberg duality follows from phenomena in string theory, where gauge theories arise as the worldvolume theories of D-branes (geometric engineering of quantum field theory). Seiberg duality is obtained for gauge theories of D-branes that stretch between two NS5-branes. The duality operation corresponds to exchanging the two NS5-branes.

See also string theory results applied elsewhere.

Formalization by derived quiver categories

Seiberg duality is formalized by equivalences of derived categories of quiver representations.

Examples

Toric duality

Toric Duality is Seiberg duality for N=1N=1 theories with toric moduli spaces.
