REVIEW

Electric-Magnetic Duality in Supersymmetric Non-Abelian Gauge Theories

High Energy Physics - Theory · Submitted 20 Nov 1994 · 21 references

Pith's verdict: The origin paper for N=1 Seiberg duality: the dual pair is genuinely new and the checks are the kind that could have failed, with the fixed-point existence assumed rather than proved — and said so in the text.

Referee report
The paper

The paper claims

Supersymmetric QCD with Nf flavors has a dual description with gauge group SU(Nf-Nc), the same flavor content, and an elementary meson, matching all 't Hooft anomalies and reproducing confinement as Higgsing.

The reading

Quantum chromodynamics, the theory of quarks and gluons, is hard to solve at low energies because the coupling grows. Supersymmetric versions of QCD are more tractable because holomorphy and exact beta functions constrain them. Seiberg studies N=1 supersymmetric SU(Nc) gauge theory with Nf quark flavors in the range where the theory is believed to flow to an interacting scale-invariant fixed point, roughly 3Nc/2 < Nf < 3Nc. In that window the theory has no particle interpretation, so it can in principle be described by more than one set of massless fields. He proposes a second description: an SU(Nf-Nc) gauge theory with Nf flavors of dual quarks plus a gauge-singlet meson field M coupled through a superpotential M q qbar. The dual quarks carry fractional baryon number and cannot be built from the original quarks, so they are genuinely new variables. The evidence is a set of consistency conditions. The 't Hooft anomalies of the global symmetry group match exactly between the two theories. The R-charges assigned to the dual fields are anomaly free and give the meson the same dimension as in the electric theory. Dualizing twice returns the original theory, with the extra meson becoming massive. Turning on a mass in one description becomes Higgsing in the other, and the flat directions map onto each other. The paper extends the construction to SO(Nc) and states the SP(Nc) case without detail. Seiberg is explicit that he cannot prove the fixed point exists for every Nf in the window; that is established only in a large-Nc expansion.
Extended reading notes

Core claim

The infrared physics of SU(Nc) supersymmetric QCD with Nf flavors in the window 3Nc/2 < Nf < 3Nc is equally well described by an SU(Nf-Nc) gauge theory with Nf dual quarks q, qbar and a gauge-singlet meson M, with superpotential W = M q qbar (Eq. 3.3). If correct, the dual quarks and gluons are non-Abelian magnetic monopoles of the electric theory, and the two theories are the same conformal field theory in different variables.

Load-bearing premise

The premise that an interacting non-Abelian Coulomb phase actually exists for every Nf in 3Nc/2 < Nf < 3Nc. Section 2 establishes a zero of the beta function only in the double limit Nc to infinity with Nf/Nc = 3 - epsilon and epsilon small, citing Banks-Zaks [17], and then states: 'We cannot prove our assumption that for every 3Nc/2 < Nf < 3Nc the theory at the origin is in a non-Abelian Coulomb phase as we described.' If the fixed point is absent or is not the one assumed for some Nf in that window, the duality statement has no common infrared theory to describe.

Original abstract

We demonstrate electric-magnetic duality in N=1 supersymmetric non-Abelian gauge theories in four dimensions by presenting two different gauge theories (different gauge groups and quark representations) leading to the same non-trivial long distance physics. The quarks and gluons of one theory can be interpreted as solitons (non-Abelian magnetic monopoles) of the elementary fields of the other theory. The weak coupling region of one theory is mapped to a strong coupling region of the other. When one of the theories is Higgsed by an expectation value of a squark, the other theory is confined. Massless glueballs, baryons and Abelian magnetic monopoles in the confining description are the weakly coupled elementary quarks (i.e.\ solitons of the confined quarks) in the dual Higgs description.

How later papers used it

501 later papers cite it

Evidence: substantial. 500 of the citing papers share no author with it, and 50 of those carry a confident label from Pith's citation classifier.

Pith read 38 of the 776 citing sentences, choosing only those whose citation markers point at this paper alone, and wrote the paraphrases from them. The summary, the counts, the evidence level, the links and the quotes come from code; the summary counts the papers listed below. A later paper is listed under a label when Pith's citation classifier gives one of its sentences that label at probability 0.8 or more (0.95 for support), Pith's reading finds that the citing paper itself did it, and a second check confirms the paraphrase against the sentence. This section lists uses only. It does not list criticism or disagreement, so their absence here says nothing about how the paper has been received. Papers that share an author with this one are listed apart, under "By the same authors". A quote is the citing authors' own sentence, shown when their paper's licence is CC BY, CC BY-SA or CC0. JSON
