Heavy $Omega_c$ and $Omega_b$ baryons in the quark model

In this contribution, we present a study of ground- and excited-state $Omega_c$ and $Omega_b$ 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 $Omega_c$ and $Omega_b$ states can be interpreted in terms of $lambda$-mode excitations.
