Possible bound states of heavy baryonium and heavy dibaryon systems

Year: 2024

Type: article

Abstract: 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 Λ ¯ Q , Ξ Q Ξ ¯ Q , Σ Q Σ ¯ Q , Ξ Q ′ Ξ ¯ Q ′ , and Ω Q Ω ¯ Q ( Q = c , b ), can form bound states. Among the heavy dibaryon systems, only the Ξ Q Ξ Q system with I = 0 and the Σ Q Σ Q systems with I = 0 and I = 1 can exist as bound states. Additionally, the Σ Q Σ ¯ Q system with I = 2 and the Σ Q Σ Q system with I = 1 are not deeply bound. Published by the American Physical Society 2024
