The strong and radiative decays of the low-lying- and-wave,,,, andbaryons are systematically studied in a constituent quark model. We find that the radiative decay modecould be very useful for us to establish the missing neutral statesand. Our calculation shows that most of those missing-mode-wave singly heavy baryons have a relatively narrow decay width of less than 30 MeV. Their dominant strong and radiative decay channels can be ideal for searching for their signals in future experiments. Theresonance may be assigned towithorwith. In general, the excitations ofandof themultiplet have similar strong decay properties. In order to identify them, angular distributions of their decays in either strong decay modes or radiative transitions should be needed.
