摘要：

In this work, we systematically study the heavy baryonium and heavy dibaryon systems using the BetheSalpeter equation in the ladder and instantaneous approximations for the kernel. Our results indicate that all the heavy baryonium systems, specifically AQ bound states. Among the heavy dibaryon systems, only the QQ system with I 1 / 4 0 and the EQEQ systems with I 1 / 4 0 and I 1 / 4 1 can exist as bound states. Additionally, the EQE<overline>Q system with I 1 / 4 2 and the EQEQ system with I 1 / 4 1 are not deeply bound. AQ,Q Q, E Q E Q , 0 Q 0 Q , and IZQIZQ (Q 1 / 4 c , b ), can form
