Magnetic discrete gauge field in the confining vacua and the supersymmetric index
نویسنده
چکیده
It has recently been argued that the confining vacua of Yang-Mills theory in the far infrared can have topological degrees of freedom given by magnetic Zq gauge field, both in the non-supersymmetric case and in the N = 1 supersymmetric case. In this short note we give another piece of evidence by computing and matching the supersymmetric index of the pure super Yang-Mills theory both in the ultraviolet and in the infrared.

Monopole 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...

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 کاملGeometric Transitions and D-term SUSY Breaking
We propose a new way of using geometric transitions to study metastable vacua in string theory and certain confining gauge theories. The gauge theories in question are N = 2 supersymmetric theories deformed to N = 1 by superpotential terms. We first geometrically engineer supersymmetry-breaking vacua by wrapping D5 branes on rigid 2-cycles in noncompact Calabi-Yau geometries, such that the cent...

We study the moduli space of vacua of four dimensional N = 1 and N = 2 supersymmetric gauge theories with the gauge groups Sp(2Nc), SO(2Nc) and SO(2Nc + 1) using the M theory fivebrane. Higgs branches of the N = 2 supersymmetric gauge theories are interpreted in terms of the M theory fivebrane and the type IIA s-rule is realized in it. In particular we construct the fivebrane configuration whic...
