Heavy $\Xi_{c/b}$ and $\Xi'_{c/b}$ baryons in the quark model

We present a study of the low-lying $\Xi_{c/b}$ and $\Xi'_{c/b}$ 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.
