چکیده

We study the physics with finite nuclear density in the framework of AdS/QCD with holographic baryon field included. Based on a mean field type approach, we introduce the nucleon density as a bi-fermion condensate of the lowest mode of the baryon field and calculate the density dependence of the chiral condensate, the nucleon mass and the ρ-meson-nucleon coupling. We observe that the chiral condensate as well as the mass of nucleon decrease with increasing nuclear density. We also consider the mass splitting of charged vector mesons in iso-spin asymmetric nuclear matter. e-mail: [email protected]. e-mail: [email protected]. e-mail: [email protected].

Meson-Nucleon Coupling from AdS/QCD

In this manuscript, a unified approach to hadron physics from holographic point of view is described. After introduction of a general setup for mesonnucleon system based on the bottom-up approach of QCD (AdS/QCD), as an illustration, we specifically examine meson-nucleon couplings. This is an example of the notion we call “holographic unification” in hadron physics. [email protected] motoi...

Jet Nuclear Modification Factor from the AdS/CFT Correspondence

We define a novel definition of the holographic light hadron jet by a separation of scales from plasma to jet, which leads to the re-emergence of the late-time Bragg peak in the instantaneous jet energy loss rate. We use the holographic energy loss of light quark and our new jet prescription in AdS/CFT to calculate the nuclear modification factor of jet for a brick of plasma (both static and ex...

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...

Weak Interaction in Holographic QCD

We present a recent proposal of a simple prescription for including low-energy weak-interactions into the framework of holographic QCD, based on the standard AdS/CFT dictionary of doubletrace deformations. This opens a new perspective on phenomenological applications of holographic QCD: calculating weak observables in the strongly coupled regime of QCD. The idea is general enough to be implemen...
