Strange Mesons In ADS/QCD

AdS/CFT duality and the holographic principle has very close links. Both in the fields of high energy or condensed matter, there are many strong coupling issues, such as quark confinement, superconductivity and so on, these problems can often be included in the scope of field theory; However, in the strongly coupled field theory problem is extremely difficult. As the AdS/CFT duality is a strong or weak duality, so this is to solve the field theory of the strong coupling opens an important window:we can study a weakly coupled string theory (or theory of gravity) to be strongly coupled field theory some of the information. Conversely, use of field theory can also help resolve some of the important theory of gravity in the strong coupling problem. Because of this, AdS/CFT duality from the beginning made great interest.QCD as an approximation of the conformal field theory, AdS/QCD holographic dual model in recent years has also been extensively studied. Results are consistent with the experimental data. After introducing the meson properties in SU(2)L (?)SU(2)R symmetrical holographic dual model, we mainly calculated vector strange meson, axial vector exotic meson and the pseudoscalar strange meson properties, including scattering constant, charge radius and form factor in SU(3)L (?)SU(3)R symmetry holographic Hard-Wall and Soft-Wall model.Study the internal structure of hadrons has been a theoretical and experimental physics research priority. According to G.A.Miller's meson transverse charge density distribution function in the infinite momentum frame, we calculated meson charge density distribution in three kinds of AdS/QCD holographic model. We conclude that the horizontal center of meson charge density distribution is related to the form factor at large momentum transfer. We give a general conclusion.
