Interpretation of the new Omega(0)(c) states via their mass and width
The masses and pole residues of the ground and first radially excited Omega(0)(c) states with spin-parities J(P) = 1/2(+), 3/2(+), as well as P-wave Omega(0)(c) with J(P) = 1/2(-), 3/27(-) are calculated by means of the ...
On the nature of the newly discovered omega states
(EPL Association, 2017-06)
The mass and residue of the ground-state, as well as the first orbital and radial excitations of the heavy Omega(Q) baryons with Q being b or c quark, for both J = 1/2 and J = 3/2 are calculated by means of the QCD two-point ...
Decay widths of the excited Omega(b) baryons
(American Physical Society, 2017-11)
The LHCb Collaboration recently observed five narrow Omega(0)(c) resonances and measured their masses and widths through the decays Omega(0)(c) -> Xi(+)(c) K-. Motivated by this discovery, and also by the fact that the ...
Analysis of the structure of Xi (1690) through its decays
The mass and pole residue of the first orbitally and radially excited Xi state as well as the ground state residue are calculated by means of the two-point QCD sum rules. Using the obtained results for the spectroscopic ...
The structure, mixing angle, mass and couplings of the light scalar f(0)(500) and f(0)(980) mesons
The mixing angle, mass and couplings of the light scalar mesons f(0)(500) and f(0)(980) are calculated in the framework of QCD two-point sum rule approach by assuming that they are tetraquarks with diquark-antidiquark ...
