Chiral Symmetry Breaking and Phase Transitions in Holographic Gauge Theories
- Physics
- 2008
We discuss the spontaneous breaking of the chiral symmetry in QCD in the framework of the string/gauge duality. We use two different holographic models of QCD. One of them is the general intersecting…
Mesons in gauge/gravity duals

Abstract.We review recent progress in studying mesons within gauge/gravity duality, in the context of adding flavour degrees of freedom to generalizations of the AdS/CFT correspondence. Our main…
Spontaneous chiral symmetry breaking in holographic soft wall models
- PhysicsPhysical Review D
- 2021
We investigate non-linear extensions of the holographic soft wall model proposed by Karch, Katz, Son and Stephanov [1] including non-minimal couplings in the fivedimensional action. The non-minimal…
Dynamics of baryons from string theory and vector dominance
- Physics
- 2007
We consider a holographic model of QCD from string theory, a la Sakai and Sugimoto, and study baryons. In this model, mesons are collectively realized as a five-dimensional U(NF) = U(1) × SU(NF)…
Towards a novel description of flavor dynamics in holographic QCD
- Physics
- 2010
D-branes with a U-shaped geometry, like the D8 flavor branes in the Sakai-Sugimoto model of QCD, are encountered frequently in holographic backgrounds. The Dirac-Born-Infeld action, which is commonly…

- Physics
- 2007
We re-analyze D8 brane embeddings in the geometry of a D4 brane wrapped on a circle that describe chiral symmetry breaking in a strongly coupled non-supersymmetric gauge theory. We argue that if the…
The CP-odd sector and $θ$ dynamics in holographic QCD

The holographic model of V-QCD is used to analyze the physics of QCD in the Veneziano large-N limit. An unprecedented analysis of the CP-odd physics is performed going beyond the level of effective…
An AdS/QCD model from tachyon condensation: II
- Physics

A simple holographic model is presented and analyzed that describes chiral symmetry breaking and the physics of the meson sector in QCD. This is a bottom-up model that incorporates string theory…
Nuclear Force from String Theory
- Physics

We compute nuclear force in a holographic model of QCD on the basis of a D4-D8 brane configuration in type IIA string theory. Repulsive core of nucleons is quite important in nuclear physics, but its…

We study N f D6-brane probes in the supergravity background dual to N c D4-branes compactified on a circle with supersymmetry-breaking boundary conditions. In the limit in which the resulting…

We discuss the incorporation of quarks in the fundamental representation of the color group into the non-critical string/gauge duality. We focus on confining theories and address this question using…

We study the low energy dynamics of pions in a gravity dual of chiral symmetry breaking. The string theory construction consists of a probe D7 brane in the Constable-Myers nonsupersymmetric…

We present a holographic dual of four-dimensional, large N_c QCD with massless flavors. This model is constructed by placing N_f probe D8-branes into a D4 background, where supersymmetry is…

We analyze the resolution of the U(1)A problem in the Sakai-Sugimoto holographic dual of large Nc QCD at finite temperature. It has been shown that in the confining phase the axial symmetry is broken…

Recently a holographic model of hadrons motivated by AdS/CFT has been proposed to fit the low energy data of mesons. We point out that the infrared physics can be developed in a more systematic…
