Light Nonabelian Monopoles and Generalized r-Vacua in Supersymmetric Gauge Theories
نویسندگان
چکیده
We study a class of N = 1 supersymmetric U(N) gauge theories and find that there exist vacua in which the low-energy magnetic effective gauge group contains multiple nonabelian factors, ∏ i SU(ri), supported by light monopoles carrying the assiciated nonabelian charges. These nontrivially generalize the physics of the so-called r-vacua found in softly broken N = 2 supersymmetric SU(N) QCD, with an effective lowenergy gauge group SU(r)×U(1)N−r. The matching between classical and quantum (r1, r2, . . .) vacua gives an interesting hint about the nonabelian duality.

Dynamical Symmetry Breaking in Supersymmetric SU(nc) and USp(2nc) Gauge Theories
We find the phase and flavor symmetry breaking pattern of each N = 1 supersymmetric vacuum of SU(nc) and USp(2nc) gauge theories, constructed from the exactly solvable N = 2 theories by perturbing them with small adjoint and generic bare hypermultiplet (quark) masses. In SU(nc) theories with nf ≤ nc the vacua are labelled by an integer r, in which the flavor U(nf ) symmetry is dynamically broke...
متن کاملNonabelian Monopoles and Confinement: New Prospects
We discuss quantum mechanical aspects of non abelian monopoles in relation to the phenomena of confinement and dynamical symmetry breaking. In supersymmetric theories there are three types of confining vacua have been found: (i) abelian dual superconductor; (ii) weakly-coupled nonabelian dual superconductor; and (iii) strongly-coupled, nonabelian Argyres-Douglas vacua. The last class of systems...
متن کاملWho Confines Quarks? - on Non-abelian Monopoles and Dynamics of Confinement
The role non-Abelian magnetic monopoles play in the dynamics of confinement is discussed by examining carefully a class of supersymmetric gauge theories as theoretical laboratories. In particular, in the so-called r-vacua of softly broken N = 2 supersymmmetric SU(nc) QCD, the Goddard-Olive-Nuyts-Weinberg monopoles appear as the dominant low-energy effective degrees of freedom. Even more interes...
متن کاملNonabelian Confinement near Nontrivial Conformal Vacua
We discuss some aspects of confinement and dynamical symmetry breaking in the so-called nonabelian Argyres-Douglas vacua, which occur very generally in supersymmetric theories. These systems are characterized by strongly-coupled nonabelian monopoles and dyons; confinement and dynamical symmetry breaking are caused by the condensation of monopole composites, rather than by condensation of single...
متن کاملMonopole Condensation and Confining Phase of N = 1 Gauge Theories Via M Theory
The fivebrane of M theory is used in order to study the moduli space of vacua of confining phase N = 1 supersymmetric gauge theories in four dimensions. The supersymmetric vacua correspond to the condensation of massless monopoles and confinement of photons. The monopole and meson vacuum expectation values are computed using the fivebrane configuration. The comparison of the fivebrane computati...
