Mass spectrum of the vector hidden charm and bottom tetraquark states
In this article, we perform a systematic study of the mass spectrum of the vector hidden charm and bottom tetraquark states using the QCD sum rules. PACS number: 12.39.Mk, 12.38.Lg
متن کاملReanalysis of the mass spectrum of the scalar hidden charm and hidden bottom tetraquark states
In this article, we study the mass spectrum of the scalar hidden charm and hidden bottom tetraquark states which consist of the axial-axial type and the vector-vector type diquark pairs with the QCD sum rules. PACS number: 12.39.Mk, 12.38.Lg
متن کاملMass spectrum of the scalar hidden charm and bottom tetraquark states
In this article, we study the mass spectrum of the scalar hidden charm and bottom tetraquark states with the QCD sum rules. The numerical results are compared with the corresponding ones from a relativistic quark model based on a quasipotential approach in QCD. The relevant values from the constituent diquark model based on the constituent diquark masses and the spin-spin interactions are also ...
متن کاملLattice QCD signal for a bottom-bottom tetraquark
Utilizing lattice QCD results for the potential of two static antiquarks and two dynamical quarks as well as quark model techniques for the dynamics of two heavy antiquarks in a cloud of two light quarks, we are provided with an accurate framework for the study of possibly existing heavy-heavylight-light tetraquarks. Among the possible quantum numbers of such a system, we find binding in only o...
متن کاملMass spectrum of the vector hidden charmed and bottomed tetraquark states
The Babar, Belle, CLEO, D0, CDF and FOCUS collaborations have discovered (or confirmed) a large number of charmonium-like states X(3940), X(3872), Y (4260), Y (4008), Y (3940), Y (4325), Y (4360), Y (4660), etc, and revitalized the interest in the spectroscopy of the charmonium states [1, 2, 3, 4]. Many possible assignments for those states have been suggested, such as multiquark states (whethe...
