The observation of five Omega(c) = 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 Omega(c) baryons and predictions for their Xi(+)(c) K- and Xi'(c)+ K- decay amplitudes within an harmonic oscillator based model, we suggest a possible solution to the Omega(c) quantum number puzzle and we extend our mass and decay width predictions to the Omega(b) states. Finally, we discuss why the set of Omega(c(b)) baryons is the most suitable environment to test the validity of three-quark and quark-diquark effective degrees of freedom.
