The strength of the interaction is defined as an effective running coupling $\\alpha$ from lattice. By considering the $\\mathrm{Q\\bar{Q}}$ and $\\mathrm{QQq}$ moving through the thermal quark-gluon plasma, we find that the interaction of heavy quarks for $\\mathrm{Q\\bar{Q}}$ is small and remains almost constant when $L<0.2\\,\\mathrm{fm}$. The strength of the interaction for $\\mathrm{QQq}$ is always less than that for $\\mathrm{Q\\bar{Q}}$ and approaches a constant when $L<0.4\\,\\mathrm{fm}$. The $\\alpha$ and the maximum of effective running coupling $\\tilde{\\alpha}$ for both $\\mathrm{Q\\bar{Q}}$ and $\\mathrm{QQq}$ decrease with increasing temperature or rapidity. Through comparison, we find that $\\mathrm{QQq}$ is more sensitive to changes in temperature and rapidity, and the interaction force between quarks is always less than that of $\\mathrm{Q\\bar{Q}}$, indicating that $\\mathrm{Q\\bar{Q}}$ is more stable than $\\mathrm{QQq}$ in the presence of temperature and rapidity.", "revisions": [ { "version": "v1", "updated": "2024-09-04T15:06:39.000Z" } ], "analyses": { "keywords": [ "thermal plasma", "heavy quarks", "thermal quark-gluon plasma", "doubly heavy baryons", "finite temperature" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
