摘要:

本文利用规范/引力对偶性研究了有限温度和速率下重夸克onium(Q̄Q)和双重重玻色子(QQq)之间的相互作用强度。我们展示该理论框架能够通过格点势能拟合同时准确描述Q̄Q和QQq。在此框架中,通过有效弦张力研究其在长距离或低温低速率下的相互作用,通过有效运行耦合研究其在短距离或高温高速率下的相互作用。此外,我们绘制了其在T-η平面上的状态图,并系统计算了它们各自的屏蔽距离。

英文摘要:

The strength of the interaction between heavy quarks is studied for heavy quarkonium ($\mathrm{Q\bar{Q}}$) and doubly heavy baryons ($\mathrm{QQq}$) at finite temperature and rapidity using the gauge/gravity duality in this paper. We show that this theoretical framework is capable of simultaneously and accurately describing both $\mathrm{Q\bar{Q}}$ and $\mathrm{QQq}$ by fitting lattice potentials. In this framework, we study their interaction at long distances or low temperature and rapidity through effective string tension, while the interaction at short distances or high temperature and rapidity is studied through effective running coupling. Additionally, we plot their state diagram in the $T-η$ plane and systematically calculate their respective screening distances.
