Baryons from instantons in holographic QCD
We consider aspects of dynamical baryons in a holographic dual of QCD that is proposed on the basis of a D4/D8-brane configuration. We construct a soliton solution carrying a unit baryon number and show that it is given by an instanton solution of four-dimensional Yang-Mills theory with fixed size. The Chern-Simons term on the flavor D8-branes plays a crucial role of protecting the instanton fr...
متن کاملHolographic melting of Heavy Baryons in Plasma with Gluon Condensation
We propose a Dirac-Born-Infeld ( DBI ) D5 vertex brane plus Nc fundamental strings configuration to describe a baryon probe in strongly coupled gauge theory with gluon condensation at finite temperature via AdS/CFT correspondence. We investigate properties of this configuration in a dilaton deformed AdS5×S background, in which IIB string theroy is dual to super Yang-Mills thery in a state with ...

متن کاملHolographic Baryons : Static Properties and Form Factors from Gauge/String Duality
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 asymptotic behavior of the soliton solution, which allows us to evaluate welldefined currents associated with the U(Nf )L × U(Nf )R chiral symmetry. Using the currents, we compute static quantities of bar...
متن کاملBaryons and the Chern-Simons term in holographic QCD with three flavors
We study dynamical baryons in the holographic QCD model of Sakai and Sugimoto in the case of three flavors and with special interest in the construction of the Chern-Simons (CS) term. The baryon classical solution in this model is given by the BPST instanton, and we carry out the collective coordinate quantization of the solution. The CS term should give rise to a first class constraint which s...
