Heavy ${\mathrm{\Omega }}_c$ and ${\mathrm{\Omega }}_b$ baryons in the quark model

In this contribution, we present a study of ground- and excited-state ${\mathrm{\Omega }}_c$ and ${\mathrm{\Omega }}_b$ baryons consisting of two strange quarks and a heavy charm or bottom quark. An analysis in the quark model shows that the recently observed excited ${\mathrm{\Omega }}_c$ and ${\mathrm{\Omega }}_b$ states can be interpreted in terms of $\lambda$-mode excitations.
