Query: Excited $\Omega$'s as heavy pentaquarks   We briefly summarize recent works on the identification of the excited
$\Omega_c$'s found by the LHCb Collaboration. Within the framework of a pion
mean-field approach, the following scenario is the most favorable: While three
of the excited $\Omega_c$'s belong to the excited baryon sextet, two of them
with the smaller decay widths can be identified as the members of the
anti-decapentaplet which is one of the lowest-lying representations. It implies
that these two $\Omega_c$'s, i.e. $\Omega(3050)$ and $\Omega(3119)$ are most
probably the exotic heavy pentaquark baryons.
