| contents | In this work, we study the properties of single-flavor heavy baryons, $Ω_{\rm ccc}$ and $Ω_{\rm bbb}$, in a strong magnetic field. For that sake, we simply treat the baryons as quark-diquark two-body systems, and a systematic formalism is developed to deal with two-body Schr$\ddot{\text o}$dinger equations in a magnetic field. It is found that: 1. The orbital properties of $Ω_{\rm bbb}$ are almost not affected by the magnetic field. 2. $Ω_{\rm ccc}$ is more tightly bound in the presence of a magnetic field. 3. The magnetic-spin effect dominates over the magnetic-orbital effect. Applying to peripheral heavy ion collisions, $Ω_{\rm ccc}$ is much better than $Ω_{\rm bbb}$ to explore the magnetic effect, and the discovery of $Ω_{\rm ccc}$ could be more promising. |
