چکیده
In this paper, we study the scalar-diquark–scalar-diquark–antiquark-type [Formula: see text] pentaquark state with QCD sum rules, predicted mass is in excellent agreement experimental data from LHCb collaboration, and supports assigning to be hidden-charm spin-parity text]. We take into account flavor mass-breaking effect, estimate spectrum of diquark–diquark–antiquark-type states strangeness

Magnetic moment of the pentaquark Θ(1540) as diquark-diquark-antiquark state with QCD sum rules
In this article, we study the magnetic moment of the pentaquark state Θ+(1540) as diquark-diquark-antiquark ([ud][ud]s̄) state with the QCD sum rules in the external weak electromagnetic field (EFSR) and the light-cone QCD sum rules (LCSR) respectively. The numerical results indicate the magnetic moment is about μΘ+ = −(0.11 ± 0.02)μN for the EFSR and μΘ+ ≈ −(0.1−0.5)μN for the LCSR. As the valu...
متن کاملDecay width of the pentaquark state Θ(1540) with QCD sum rules
In this article, we study the decay width of the pentaquark state Θ(1540) with the QCD sum rules approach. The numerical results indicate the strong coupling constant gΘNK is about |gΘNK | = 0.26± 0.7, which can explain the narrow decay width naturally. PACS : 12.38.Aw, 12.38.Lg, 12.39.Ba, 12.39.-x
متن کاملMass of the charm-quark from QCD sum rules
Relativistic and non-relativistic ratios of Laplace transform QCD moment sum rules for charmonium are used in order to determine the value of the on-shell charmquark mass. The validity of the non-relativistic version of QCD sum rules in this particular application is discussed. After using current values of the perturbative and non-perturbative QCD parameters, as well as experimental data on th...
متن کاملAnalysis of the X(1576) as a tetraquark state with the QCD sum rules
In this letter, we take the point of view that the X(1576) be tetraquark state which consists of a scalar-diquark and an anti-scalar-diquark in relative P -wave, and calculate its mass in the framework of the QCD sum rules approach. The numerical value of the mass mX = (1.66±0.14)GeV is consistent with the experimental data, there may be some tetraquark component in the vector meson X(1576). PA...
متن کاملDiquark-Antidiquark with open charm in QCD sum rules
Using the QCD sum rule approach we investigate the possible four-quark structure of the recently observed charmed scalar mesons D 0(2308) (BELLE) and D 0,+ 0 (2405) (FOCUS) and also of the very narrow D sJ (2317), firstly observed by BABAR. We use diquak-antidiquark currents and work to the order of ms in full QCD, without relying on 1/mc expansion. Our results indicate that a fourquark structu...
