We consider instanton effects in a non-supersymmetric gauge theory obtained by marginal deformations of the = 4 SYM. This gauge theory is expected to be dual to type IIB string theory on the AdS5 times deformed-S5 background. From an instanton calculation in the deformed gauge theory we extract the prediction for the dilaton-axion field τ in dual string theory. In the limit of small deformations where the supergravity regime is valid, our instanton result reproduces the expression for τ of the…

Giants on deformed backgrounds

We study giant graviton probes in the framework of the three-parameter deformation of the AdS5 × S 5 background. We examine both the case when the brane expands in the deformed ˜ S 5 part of the

Non-conformality of &ggr; i ?> -deformed 𝒩 = 4 SYM theory

We show that the γi-deformation, which was proposed as candidate gauge theory for a non-supersymmetric three-parameter deformation of the anti-de Sitter / conformal field theory correspondence, is

Duality and models of supersymmetry breaking

Duality is often most clearly manifest in supersymmetric theories, where the rigid mathematical structure affords good control over the behaviour of the system. In many real-world applications, and

(Non)-supersymmetric Marginal Deformations from Twistor String Theory

Proof of all-order finiteness for planar beta-deformed Yang-Mills

We study a marginal deformation of N = 4 Yang–Mills, with a real deformation parameter β. This β-deformed model has only N = 1 supersymmetry and a U(1)×U(1) flavor symmetry. The introduction of a new

Holographic backgrounds from D-brane probes

The gauge/string correspondence provides a non-perturbative definition of string theory and hence quantum gravity in some backgrounds, making it possible to translate statements about strongly

On β – deformations and Noncommutativity

We elucidate the connection between the N = 1 β–deformed SYM theory and noncommutativity. Our starting point is the T–duality generating transformation involved in constructing the gravity duals of

Instanton calculations in the β-deformed AdS/CFT correspondence

We consider non-perturbative effects in the β-deformed = 4 supersymmetric gauge theory in the context of the AdS/CFT correspondence. We concentrate on certain types of the n-point correlation

The one-instanton contributions to various correlation functions of superconformal currents in four-dimensional = 4 supersymmetric SU(2) Yang-Mills theory are evaluated to the lowest order in

Exact results in planar = 1 superconformal Yang-Mills theory

In the β-deformed = 4 supersymmetric SU(N) Yang-Mills theory we study the class of operators J = Tr(ΦiJΦk), i≠k and compute their exact anomalous dimensions for N,J→∞. This leads to a prediction for

On exactly marginal deformations of N=4 SYM and type IIB supergravity on AdS(5) x S**5

= 4 supersymmetric Yang-Mills theory with gauge group SU(N) (N ≥ 3) is believed to have two exactly marginal deformations which break the supersymmetry to = 1. We discuss the construction of the

Gauge-string duality for superconformal deformations of N=4 super Yang-Mills theory

We analyze in detail the relation between an exactly marginal deformation of N=4 SYM - the Leigh-Strassler or ``beta-deformation'' - and its string theory dual (recently constructed in

String theory dual of the β-deformed gauge theory

We consider the AdS/CFT correspondence between the β-deformed supersymmetric gauge theory and the type IIB string theory on the Lunin-Maldacena background. Guided by gauge theory results, we modify
