Heavy ${\mathrm{\Xi }}_{c\mathrm{/}b}$ and ${\mathrm{\Xi }}_{c\mathrm{/}b}^{\mathrm{\prime }}$ baryons in the quark model

We present a study of the low-lying ${\mathrm{\Xi }}_{c\mathrm{/}b}$ and ${\mathrm{\Xi }}_{c\mathrm{/}b}^{\mathrm{\prime }}$ baryon states based on masses, strong and radiative decays. In a harmonic oscillator quark model analysis it is found that the majority of the detected states can be interpreted as $S$- and $P$-wave excitations.
