Testing the doubly charged charm-strange tetraquarks
The spectroscopic parameters and decay channels of the doubly charged scalar, pseudoscalar and axial-vector charm-strange tetraquarks Z((c) over bars) = [sd][(uc) over bar] are explored within framework of the QCD sum rule ...
Resonance Y(4660) as a vector tetraquark and its strong decay channels
(American Physical Society, 2018-09)
The spectroscopic parameters and partial widths of the strong decay channels of the vector meson Y(4660) are calculated by treating it as a bound state of a diquark and antidiquark. The mass and coupling of the JPC=1 - ...
On the nature of Ξc(2930)
The single charmed excited Ξc(2930) state was discovered many years ago by the BABAR Collaboration and recently confirmed by Belle experiment. However, both these experiments, unfortunately, could not fix the quantum numbers ...
