Meson spectrum and tetraquarks through an AdS/QCD inspired potential
نویسنده
چکیده
AdS/QCD correspondence allows to compute the quark-antiquark potential in the static limit. We use this piece of information together with the Salpeter equation (Schroedinger equation with relativistic kinematics) and a short range hyperfine splitting potential to describe the bound states of quark-antiquark. Comparison with experiment permits to fit the parameters of the model, namely the quark masses and the quark potential parameters. A discussion of heavy tetraquark masses, prompted by the hypothesis of a diquark-antidiquark structure for the puzzling state X(3872), is also presented.

متن کاملTetraquarks in the 1/N expansion and meson-meson resonances
Diquarks are found to have the right degrees of freedom to describe the tetraquark poles in hiddencharm to open-charm meson-meson amplitudes. Compact tetraquarks result as intermediate states in non-planar diagrams of the 1/N expansion and the corresponding resonances are narrower than what estimated before. The proximity of tetraquarks to meson-thresholds has an apparent role in this analysis ...
متن کاملRegge spectrum from holographic models inspired by OPE
The problem of obtaining the Regge-like behaviour for meson mass spectrum in the hard-wall AdS/QCD models is addressed. We show that the problem can be solved by a simple incorporation of the effects of local vacuum condensates into such models. The slope of trajectories turns out to be determined by the local condensate of dimension 2 that is absent in the standard Operator Product Expansion. ...
متن کاملMeson Spectra from an Effective Light Cone Qcd-inspired Model
Abstract I present some recent applications of a light cone QCD-inspired model with the mass squared operator consisting of a harmonic oscillator potential as confinement in the meson spectra. The model gives an universal and satisfactory description of both singlet and triplet states of S-wave mesons. In the present work P -wave Ds mesons are also investigated. The mass of the recently found m...
متن کاملMeson-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...
