Linear Confinement and AdS/QCD
نویسندگان
چکیده
In a theory with linear confinement, such as QCD, the masses squared, mn,S, of mesons with high spin S or high radial excitation number n are expected, from semiclassical arguments, to grow linearly with S and n. We show that this translates into a strong constraint on the infrared behavior of a putative 5-dimensional theory holographically dual to QCD (AdS/QCD). In the simplest model which obeys such a constraint we find mn,S ∼ (n + S).

Confinement and Chiral Symmetry, a Lattice QCD test of AdS/QCD
We use lattice QCD simulations to test some of the predictions of proposed AdS/QCD (holographic) duals for QCD. In particular, these duals predict that the scale of chiral symmetry breaking (χSB) can be varied independently from that of confinement, with the proviso that the scale of χSB cannot be longer than that of confinement. We simulate lattice QCD with 2 quarks in the fundamental represen...
متن کاملAdS/QCD and Type 0 String Theory
We study gauge/string duality with flavor degrees of freedom in type 0B string theory. We construct a model by placing the Nf probe D9−/anti-D9− brane pairs in the background of the Nc electric D3branes. This model has some features in common with QCD, as in AdS/QCD model. By analyzing the effective action, we obtain the linear confinement behavior for the masses of the highly excited spin1 mes...
متن کاملDynamical Soft-Wall AdS/QCD
We present a solution of the five-dimensional gravity-dilaton-tachyon equations of motion with a pure AdS5 metric and a quadratic dilaton and linear tachyon in conformal coordinates. This leads to an infrared soft wall model where the dilaton profile gives rise to linear Regge trajectories for the four-dimensional mass spectrum of the dual gauge theory. Even though our approach is phenomenologi...
متن کامل∆ resonances : quark models , chiral symmetry and AdS / QCD
The mass spectrum of ∆ resonances is compared to predictions based on three quark-model variants, to predictions assuming that chiral symmetry is restored in high-mass baryon resonances, and to predictions derived from AdS/QCD. The latter approach yields a nearly perfect agreement when the confinement property of QCD is modeled by a soft wall in AdS. PACS: 11.25.Tq Gauge/string duality, 11.30.R...
متن کاملAdS/CFT correspondence and coincident D-6-branes
A relation between confinement and Maldacena conjecture is briefly discussed. The gauge symmetry enhancement for two coincident D-6-branes is analyzed from the viewpoint of the hypermultiplet low-energy effective action given by the N=2 supersymmetric non-linear sigma-model with the Eguchi-Hanson (ALE) target space. The most attractive mechanism of color confinement in QCD is known to be the du...
