“…The gaugino condensation spontaneously breaks Z 2N further down to Z 2 . Accordingly, domain walls are formed at epochs of the condensations in the early universe [3,4,5,6,7]. If the gaugino condensation occurs before the inflation, the domain walls are diluted away by the subsequent exponential expansion, and there is no cosmological remnant of the walls in the observable universe.…”

If gaugino condensations occur in the early universe, domain walls are produced as a result of the spontaneous breaking of a discrete R symmetry. Those domain walls eventually annihilate with one another, producing the gravitational waves. We show that the gravitational waves can be a probe for measuring the gravitino mass, if the constant term in the superpotential is the relevant source of the discrete R symmetry breaking.

“…That is to say, the axion Lagrangian (26) can be rewritten in terms of a two-index field. The topological charge density, to which the axion is coupled in (26), is rewritten in terms of a three-index field C µνα (21). It is intriguing to understand what happens with these three-and two-index fields after they are coupled to each other (see also a related discussions in [37]).…”

Large N c pure gluodynamics was shown to have a set of metastable vacua with the gluonic domain walls interpolating between them. The walls may separate the genuine vacuum from an excited one, or two excited vacua which are unstable at finite N c . One may attempt to stabilize them by switching on the axion field. We study how the light quarks and the axion affect the structure of the domain walls. In pure gluodynamics (with the axion field) the axion walls acquire a very hard gluonic core. Thus, we deal with a wall "sandwich" which is stable at finite N c . In the case of the minimal axion, the wall "sandwich" is in fact a "2π" wall, i.e., the corresponding field configuration interpolates between identical hadronic vacua. The same properties hold in QCD with three light quarks and very large N c . However, in the realistic case of three-color QCD the phase corresponding to the axion field profile in the axion wall is screened by a dynamical phase associated with the η ′ , so that the gluon component of the wall is not excited. We propose a toy Lagrangian which models these properties and allows one to get exact solutions for the domain walls.

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/CFT correspondence and its extension both to gauge theories in different spacetime dimensions with sixteen supercharges and to more realistic situations with less supersymmetry. We discuss the different options of interest: placing Dbranes at singularities and wrapping D-branes in calibrated cycles of special holonomy manifolds. We finally present an outline of a number of non-perturbative phenomena in non-Abelian gauge theories as seen from supergravity.
