Radial Excitations of the Decuplet Baryons
read the original abstract
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 theoretical predictions. The results for the masses of the ground state particles as well as the excited $ \Delta $ and $ \Sigma^{*} $ states are in good consistency with experimental data. Our results on the excited $ \Xi^{*} $ and $ \Omega^{-} $ states reveal that the experimentally poorly known $ \Xi(1950) $ and $ \Omega^{-}(2250) $ can be assigned as the first excited states in $ \Xi^{*} $ and $ \Omega^{-} $ channels, respectively.

Probing the hadronic molecular nature of the $\Omega(2012)$, $\Omega(2380)$, and $\Omega_c(3120)$ via femtoscopy correlation functions
Correlation function calculations with coupled-channel potentials produce low-momentum enhancements that the authors interpret as signatures of the molecular structure of Ω(2012), Ω(2380), and Ωc(3120).

Probing the hadronic molecular nature of the $\Omega(2012)$, $\Omega(2380)$, and $\Omega_c(3120)$ via femtoscopy correlation functions
Numerical correlation functions computed from effective potentials exhibit enhancements that indicate the hadronic molecular nature of the Ω(2012), Ω(2380), and Ωc(3120) resonances.
