Analysis of the structure of $$\Xi (1690)$$ Ξ(1690) through its decays
Abstract The mass and pole residue of the first orbitally and radially excited $$ \Xi $$ Ξ 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 parameters, the strong coupling constants relevant to the deca...
