Description
Models based on chiral symmetry predict the baryonic states with exotic quantum
numbers (pentaquarks) that have relatively low masses and small widths. We shall
briefly review both theoretical and experimental status of a possibility of exotica in
the light sector. Next we shall show how to extend chiral models to baryons with one
heavy quark and show that one may expect exotic states also in this case. Finally we
shall try to interpret recently discovered by the LHCb collaboration five Omega^*_c
resonances in terms of regular and exotic excitations of the ground state Omega_c.
