From ALE-instanton Moduli to Super Yang-Mills Theories via Branes
نویسنده
چکیده
A large class of equivalence relations between the moduli spaces of instantons on ALE spaces and the Higgs branches of supersymmetric Yang-Mills theories, are found by means of a certain kind of duality transformation between brane configurations in superstring theories. 4d, N=2 and 5d, N=1 supersymmetric gauge theories with product gauge groups turn out to correspond to the ALE-instanton moduli of type II B and type II A superstring theories, respectively. PACS: 11.25.Sq, 11.30.Pb

N = 1 / 2 gauge theory and its instanton moduli space from open strings in R - R background ∗
We derive the four dimensional N = 1/2 super Yang-Mills theory from tree-level computations in RNS open string theory with insertions of closed string Ramond-Ramond vertices. We also study instanton configurations in this gauge theory and their ADHM moduli space, using systems of D3 and D(–1) branes in a R-R background.

متن کاملInstantons in Deformed Super Yang-Mills Theories
We study the instanton effective action in deformed four-dimensional N = 2 and N = 4 super Yang-Mills (SYM) theories. These deformed gauge theories are defined on the D-brane world-volume in the presence of constant, self-dual Ramond-Ramond (R-R) 3-form field strength background F which is scaled as (2πα′) 1 2F = fixed in the zero-slope limit α′ → 0. The instanton effective action is obtained b...
متن کاملInstantons in N = 2 magnetized D–brane worlds
In a toroidal orbifold of type IIB string theory we study instanton effects in N = 2 super Yang-Mills theories engineered with systems of wrappedmagnetized D9 branes and Euclidean D5 branes. We analyze the various open string sectors in this brane system and study the 1-loop amplitudes described by annulus diagrams with mixed boundary conditions, explaining their rôle in the stringy instanton c...
متن کاملNew M(atrix)-models for Commutative and Noncommutative Gauge Theories
We propose a M(atrix) model for N = 4 SU(k) Super-Yang-Mills theory compactified on T 4. In this model it is possible to make T 4 noncommutative and it is easy to turn on all 6 components of the noncommutativity on T 4. The action of S-duality on the noncommutativity parameters is also manifest. The M(atrix)-model is given by the large N limit of a σ-model on T 2 whose target space is the modul...
