Radial excitations of the decuplet baryons
The ground and first excited states of the decuplet baryons are studied using the two-point QCD sum rule approach. The mass and residue of these states are computed and compared with the existing experimental data and other ...
Treating Z(c)(3900) and Z(4430) as the ground state and first radially excited tetraquarks
(American Physical Society, 2017-08-29)
Exploration of the resonances Z(c)(3900) and Z(4430) are performed by assuming that they are the ground state and first radial excitation of the same tetraquark with J(P) = 1(+). The mass and current coupling of the Zc(3900) ...
Spectroscopic parameters and decays of the resonance Z(b)(10610)
The resonance Zb(10610) is investigated as the diquark-antidiquark Zb = [bu][(b) over bar(d) over bar] state with spin-parity J(P) = 1(+). The mass and current coupling of the resonance Z(b)(10610) are evaluated using QCD ...
