Instantons, Three Dimensional Gauge Theories, and Monopole Moduli Spaces
We calculate instanton corrections to three dimensional gauge theories with N = 4 and N = 8 supersymmetry and SU(n) gauge groups. The N = 4 results give new information about the moduli space of n BPS SU(2) monopoles, including the leading order non-pairwise interaction terms. A few comments are made on the relationship of the N = 8 results to membrane scattering in matrix theory.
متن کاملMonopole Operators in N = 4 Chern-simons Theories and Wrapped M2-branes
Monopole operators in Abelian N = 4 Chern-Simons theories described by circular quiver diagrams are investigated. The magnetic charges of non-diagonal U(1) gauge symmetries form the SU(p) × SU(q) root lattice where p and q are numbers of untwisted and twisted hypermultiplets, respectively. For monopole operators corresponding to the roots, we propose a correspondence between the monopole operat...
متن کاملUnoriented D-brane Instantons vs Heterotic worldsheet Instantons
We discuss Fermi interactions of four hyperini generated by “stringy” instantons in a Type I / Heterotic dual pair on T 4/Z2.
متن کاملStringy Instantons in IIB Brane Systems
In this note, we study D-brane instantons which intersect N = 1 supersymmetric configurations of space-filling D-branes in general Calabi-Yau compactifications of type IIB string theory. Our focus is on rigid “stringy instantons” – those which cannot be interpreted as Yang-Mills instantons in a non-Abelian gauge group on any stack of space-filling D-branes. We show that their contributions to t...
متن کاملMagnetic Monopole Content of Hot Instantons
Although many qualitative features of QCD are well described by a vacuum state dominated by an instanton “liquid’, confinement appears to be an exception [1]. Instead, magnetic monopoles are thought to be the crucial ingredient. This raises the question of how magnetic degrees of freedom can be incorporated into (or reconciled with) an instanton “liquid”. A recent step in this direction was tak...
