Spectroscopy of heavy baryons

We present a study of mass spectra and electromagnetic couplings of $S$- and $P$-wave heavy baryons in the framework of a non-relativistic harmonic oscillator quark model. Particular attention is paid to the properties of heavy cascade baryons, ${\mathrm{\Xi }}_Q$ and ${\mathrm{\Xi }}_Q^{\mathrm{\prime }}$.
