We study baryons of arbitrary isospin in a stringy holographic QCD model. In this D4-D8 holographic setting, the flavor symmetry is promoted to a gauge symmetry in the bulk, and produces, as KK modes of the gauge field, pions and spin one mesons of low energy QCD. Baryons of arbitrary isospins are represented as instanton solitons with isospin and spin quantum numbers locked, in a manner similar to the Skyrmion model. The soliton picture leads to a natural effective field theory of arbitrary… 
Electromagnetic Baryon Form Factors from Holographic QCD
In the holographic model of QCD suggested by Sakai and Sugimoto, baryons are chiral solitons sourced by D4 instantons in bulk of size 1/\sqrt{\lambda} with \lambda=g^2N_c. We quantize the D4
Holographic aspects of three dimensional QCD from string theory
We study two aspects of 3D QCD with massless fermions in a holographic set-up from string theory, based on D3/D7 branes; parity anomaly and baryons as baby Skyrmions. We first give a novel account of
Comments on baryons in holographic QCD
We generalize the description of baryons as instantons of Sakai-Sugimoto model to the case where the flavor branes are non-anti-podal. The later corresponds to quarks with a ``string endpoint mass''.
Nuclear Force from String Theory
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
A matrix model for baryons and nuclear forces
We propose a new matrix model describing multi-baryon systems. We derive the action from open string theory on the wrapped baryon vertex D-branes embedded in the D4-D8 model of large Nc holographic
A holographic model for large N thermal QCD
We summarize the dual gravity description for a thermal gauge theory, reviewing the key features of our holographic model of large N QCD (Mia et al 2010 Nucl. Phys. B 839 187, Mia et al 2010 Phys.
Holographic Baryons : Static Properties and Form Factors from Gauge/String Duality(Nuclear Physics)
In this paper, we study properties of baryons by using a holographic dual of QCD on the basis of the D4/D8-brane configuration, where baryons are described by a soliton. We first determine the
Nuclear states and spectra in holographic QCD
Abstract A new method to study nuclear physics via holographic QCD is proposed. Multiple baryons in the Sakai-Sugimoto background are described by a matrix model which is a low energy effective
Properties of the Vacuum in Models for QCD: Holography vs. Resummed Field Theory. A Comparative Study.
This Thesis is dedicated to a comparison of the two means of studying the electromagnetic properties of the QCD vacuum -- holography and resummed field theory. In the UV range the non-pertubative QCD
Baryonic response of dense holographic QCD
The response function of a homogeneous and dense hadronic system to a time-dependent (baryon) vector potential is discussed for holographic dense QCD (D4/D8 embedding) both in the confined and


Low energy hadron physics in holographic QCD
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
Dynamics of baryons from string theory and vector dominance
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)
More on a holographic dual of QCD
We investigate the interactions among the pion, vector mesons and external gauge fields in the holographic dual of massless QCD proposed in a previous paper [T. Sakai and S. Sugi-moto, Prog. Theor.
The chiral model of Sakai-Sugimoto at finite baryon density
In the context of holographic QCD we analyze Sakai-Sugimoto's chiral model at finite baryon density and zero temperature. The baryon number density is introduced through compact D4 wrapping S4 at the
Chiral Dynamics of Baryons from String Theory
We study baryons in a holographic model of QCD by Sakai and Sugimoto, realized as small instantons with fundamental string hairs. We introduce an effective field theory of the baryons in the
Nucleon form factors and hidden symmetry in holographic QCD
The vector dominance of the electromagnetic form factors both for mesons and baryons arises naturally in holographic QCD, where both the number of colors and the 't Hooft coupling are taken to be
Baryons from instantons in holographic QCD
We consider aspects of dynamical baryons in a holographic dual of QCD that is formulated on the basis of a D4/D8-brane configuration. We construct a soliton solution carrying a unit baryon number and
Response of Holographic QCD to Electric and Magnetic Fields
We study the response of the Sakai-Sugimoto holographic model of large Nc QCD at nonzero temperature to external electric and magnetic fields. In the electric case we find a first-order
Brane-Induced Skyrmions Baryons in Holographic QCD
We study baryons in holographic QCD with D4/D8/D8 multi D brane system. In holographic QCD, the baryon appears as a topologically non-trivial chiral soliton in a fourdimensional effective theory of
Glueball decay in holographic QCD
Using holographic QCD based on D4-branes and D8-anti-D8-branes, we have computed couplings of glueballs to light mesons. We describe glueball decay by explicitly calculating its decay widths and
