摘要

在这项工作中，我们利用 AdS/CFT 对应关系来研究三重重子在各向异性背景下的行为。从三个夸克的总作用开始，我们推导出了三夸克系统的平衡方程，并计算了分离距离和势能。我们的结果表明，随着各向异性系数a的增大，A构型和B构型的分离距离和势能都在持续减小。这表明各向异性背景的存在促进了三夸克系统的消解。此外，我们还比较了 A 构型和 B 构型的势能，发现 A 构型的势能略小，这表明它比 B 构型更稳定。

The potential of QQQ in the anisotropic background

In this work, we use the AdS/CFT correspondence to study the behavior of a triply heavy baryon within anisotropic backgrounds. Beginning with the total action of the three quarks, we derive the balance equation for the three-quark system and compute the separation distance and potential energy. Our results reveal a consistent decrease in both the separation distance and potential energy for the A configuration and the B configuration as the anisotropy coefficient a increases. This suggests that the presence of an anisotropic background promotes the dissolution of the three-quark system. Additionally, we compare the potential energies of the A and B configurations and observe that the A configuration has a slightly smaller potential energy, suggesting greater stability compared to the B configuration.
