Multi-instanton calculus in N=2 supersymmetric gauge theory.
The Seiberg-Witten solution of N = 2 supersymmetric SU(2) gauge theory may be viewed as a prediction for the infinite family of constants {Fn} measuring the n-instanton contribution to the prepotential F . Here we examine the instanton physics directly, in particular the contribution of the general self-dual solution of topological charge n constructed by Atiyah, Drinfeld, Hitchin and Manin (AD...
متن کاملMulti-Instanton Corrections to Superpotentials in Type II Compactifications
We consider two simple examples of multi-instanton configurations in type II 4d N = 1 superstring compactifications. The first one involves O(1) and U(1) D2instantons embedded in T /(Z2 × Z2) geometry with SU(4) gauge symmetry coming from D6-branes and the second is related to quiver gauge theory of orientifolded orbifold of conifold containing fractional D(-1)-instantons and D3-branes. The add...
متن کاملSuperpotentials of N = 1 Supersymmetric Gauge Theories from M - theory
We consider brane configurations in M-theory describing N = 1 supersymmetric gauge theories. Using the parametric representation of the brane configurations, we calculate the superpotentials for various cases including multiple gauge groups or fermions. For SU(n) N = 1 SQCD with Nf fermion case (Nf < Nc), we find that the superpotential from M-theory and the gauge theory agree precisly. This gi...
متن کاملAnomalies in Instanton Calculus
I develop a formalism for solving topological field theories explicitly, in the case when the explicit expression of the instantons is known. I solve topological Yang-Mills theory with the k = 1 Belavin et al. instanton and topological gravity with the Eguchi-Hanson instanton. It turns out that naively empty theories are indeed nontrivial. Many unexpected interesting hidden quantities (puncture...
متن کاملMulti-instanton calculus in N=2 supersymmetric gauge theory. II. Coupling to matter.
We further discuss the N = 2 superinstantons in SU (2) gauge theory, obtained from the general self-dual solutions of topological charge n constructed by Atiyah, Drinfeld, Hitchin and Manin (ADHM). We realize the N = 2 supersymmetry algebra as actions on the superinstanton moduli. This allows us to recast in concise superfield notation our previously obtained expression for the exact classical ...
