The Ω_(c)-puzzle solved by means of spectrum and strong decay amplitude predictions

The observation of new $\Omega_{c}=ssc$ states by LHCb \cite{Aaij:2017nav} and the confirmation of four of them by Belle \cite{Yelton:2017qxg} may represent an important milestone in our understanding of the quark organization inside hadrons. By providing results for the spectrum of $\Omega_{c(b)}$ baryons and predictions for their $\Xi _{c(b)}^{+}K^{-}$ decay channels, we suggest a possible solution to the $\Omega_{c}$ quantum number puzzle. We also discuss why the set of $\Omega_{c(b)}$ baryons are the most suitable environment to test the validity of three-quark and quark-diquark effective degrees of freedom. Finally, we calculate the masses and the partial decay widths of the $\Xi_b(6227)$ and $\Sigma_b(6097)$ states, just observed by LHCb \cite{Aaij:2018yqz,Aaij:2018tnn}. Our results are in good agreement with LHCb experimental data.
