Lattice QCD Evidence for Exotic Tetraquark Resonance
We study the manifestly exotic tetraquark D s0 cus̄d̄ and the scalar tetraquark f0 udūd̄ in SU(3)c anisotropic quenched lattice QCD. We adopt the O a -improved Wilson (clover) fermion at β 5 75 on 123 96 with renormalized anisotropy as at 4, and investigate the correlator of the four-quark (4Q) system, cus̄d̄, with various quark masses including the idealized SU(4) f case. For f0 udūd̄ etc., we only ...
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 کاملOn tetraquark meson states
It is suggested that the narrow meson state seen in the the SELEX experiment is a (cs̄ss̄) tetraquark state. Characteristics of other possible tetraquarks formed out of c and s quarks and antiquarks are considered. SELEX experiment has reported [1] a puzzling narrow meson state at a mass of 2632.6± 1.6 MeV/c which decays preferentially to D s (cs̄) + η(548) rather than to D(cd̄)+K or D(cū)+K. In th...
متن کاملMass spectrum of the scalar hidden charmed and bottomed tetraquark states
In this article, we study the mass spectrum of the scalar hidden charmed and bottomed tetraquark states with the QCD sum rules. The numerical results are compared with the corresponding ones from the potential quark model. 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 ...
