- In this work, we systematically study the heavy baryonium and heavy dibaryon systems using the Bethe-Salpeter equation in the ladder and instantaneous approximations for the kernel. Our results indicate that all the heavy baryonium systems, specifically $Λ_Q\barΛ_Q$, $Ξ_Q\barΞ_Q$, $Σ_Q\barΣ_Q$, $Ξ'_Q\barΞ'_Q$, and $Ω_Q\barΩ_Q$ ($Q=c, b$), can form bound states. Among the heavy dibaryon systems, only the $Ξ_QΞ_Q$ system with $I=0$ and the $Σ_QΣ_Q$ systems with $I=0$ and $I=1$ can exist as bound states. Additionally, the $Σ_Q\barΣ_Q$ system with $I=2$ and the $Σ_QΣ_Q$ system with $I=1$ are not deeply bound.
