Microscopic Pictures of Dynamical Symmetry Breaking in Supersymmetric SU(nc), USp(2nc) and SO(nc) Theories
نویسنده
چکیده
Several distinct mechanisms of confinement and dynamical symmetry breaking (DSB) are identified, in a class of supersymmetric SU(nc), USp(2nc) and SO(nc) gauge theories. In some of the vacua, the magnetic monopoles carrying nontrivial flavor quantum numbers condense, causing confinement and symmetry breaking simultaneously. In more general classes of vacua, however, the effective low-energy degrees of freedom are found to be constituents of the monopoles dual (magnetic) quarks. These magnetic quarks condense and give rise to confinement and DSB. We find two more important classes of vacua, one is in various universality classes of nontrivial superconformal theories (SCFT), another in free-magnetic phase.

Dynamics of Supersymmetric SU(nc) and USp(2nc) Gauge Theories
We study dynamical flavor symmetry breaking in the context of a class of N = 1 supersymmetric 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. We find that the flavor U(nf ) symmetry in SU(nc) theories is dynamically broken to U(r) × U(nf − r) groups for nf ≤ nc. In the ...
متن کاملDynamical 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 کاملConfinement and Flavor Symmetry Breaking via Monopole Condensation
We discuss dynamics of N = 2 supersymmetric SU(nc) gauge theories with nf quark hypermultiplets. Upon N = 1 perturbation of introducing a finite mass for the adjoint chiral multiplet, we show that the flavor U(nf ) symmetry is dynamically broken to U(r) × U(nf − r), where r ≤ [nf/2] is an integer. This flavor symmetry breaking occurs due to the condensates of magnetic degrees of freedom which a...
متن کاملDuality of Sp(2Nc) and SO(Nc) Supersymmetric Gauge Theories with Adjoint Matter
We discuss electric-magnetic duality in two new classes of supersymmetric Yang-Mills theories. The models have gauge group Sp(2Nc) or SO(Nc) with matter in both the adjoint and defining representations. By perturbing these theories with various superpotentials, we find a variety of new infrared fixed points with dual descriptions. This work is complementary to that of Kutasov and Schwimmer on S...
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...
