Abstract
We briefly summarize recent works on the identification of the excited '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 '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 's, i.e. and are most probably the exotic heavy pentaquark baryons.
