Gauge/String Duality in Confining Theories
This is the content of a set of lectures given at the “XIII Jorge André Swieca Summer School on Particles and Fields”, Campos do Jordão, Brazil in January 2005. They intend to be a basic introduction to the topic of gauge/gravity duality in confining theories. We start by reviewing some key aspects of the low energy physics of non-Abelian gauge theories. Then, we present the basics of the AdS/C...
متن کاملConfining strings in SU(N) gauge theories
We calculate the string tensions of k-strings in SU(N) gauge theories in both 3 and 4 dimensions. We do so for SU(4) and SU(5) in D=3+1, and for SU(4) and SU(6) in D=2+1. In D=3+1, we find that the ratio of the k = 2 string tension to the k = 1 fundamental string tension is consistent, within quite small errors, with both the M(-theory)QCD-inspired conjecture that σk ∝ sin(πk/N) and with ‘Casim...
متن کاملBulk Dynamics in Confining Gauge Theories
We consider gauge/string duality (in the supergravity approximation) for confining gauge theories. The system under scrutiny is a 5-dimensional consistent truncation of type IIB supergravity obtained using the Papadopoulos-Tseytlin ansatz with boundary momentum added. We develop a gauge-invariant and sigma-modelcovariant approach to the dynamics of 5-dimensional bulk fluctuations. For the Malda...
متن کاملNew Confining N = 1 Supersymmetric Gauge Theories ∗
We examine N = 1 supersymmetric gauge theories which confine in the presence of a tree-level superpotential. We show the confining spectra which satisfy the ’t Hooft anomaly matching conditions and give a simple method to find the confining superpotential. Using this method we fix the confining superpotentials in the simplest cases, and show how these superpotentials are generated by multi-inst...
متن کاملSemiclassical spinning strings and confining gauge theories
We study multi-charged rotating string states on Type IIB regular backgrounds dual to confining SU (N) gauge theories with (softly broken) N = 1 supersymmetry, in the infra red regime. After exhibiting the classical energy/charge relations for the folded and circular two-charge strings, we compute in the latter case the one loop sigma-model quantum correction. The classical relation has an expa...
