The Ω<sub>c</sub>-puzzle solved by means of quark model predictions
The observation of five Ω<sub>c</sub> = ssc states by LHCb [Aaij et al. Phys. Rev. Lett. 118, 182001; (2017)] and the confirmation of four of them by Belle [Yelton et al. Phys. Rev. D 97, 051102; (2018)], may represent an important milestone in our understanding of the quark organization...

| description |
The observation of five Ω<sub>c</sub> = ssc states by LHCb [Aaij et al. Phys. Rev. Lett. 118, 182001; (2017)] and the confirmation of four of them by Belle [Yelton et al. Phys. Rev. D 97, 051102; (2018)], may represent an important milestone in our understanding of the quark organization inside hadrons. By providing results for the spectrum of Ω<sub>c</sub> baryons and predictions for their Ξ<sub>c</sub>⁺ K⁻ and Ξ'<sub>c</sub>⁺ K⁻ decay amplitudes within an harmonic oscillator based model, we suggest a possible solution to the Ω<sub>c</sub> quantum number puzzle and we extend our mass and decay width predictions to the Ω<sub>b</sub> states. Finally, we discuss why the set of Ω<sub>c(b)</sub> baryons is the most suitable environment to test the validity of three-quark and quark–diquark effective degrees of freedom. |
