摘要

我们利用量子/引力对偶性来研究重离子对撞中双重重子在有限速度和温度下的性质。我们详细研究了快速性对弦断裂和屏蔽的影响，并将这些影响与的结果进行了比较。计算结果表明，在约束状态下，和的弦断裂距离很接近，而速度和温度对弦断裂的影响并不显著。一个有趣的结果表明，在足够高的温度和速度下无法确定。然而，只要分离距离足够小，在任何条件下都可以存在。此外，我们还比较了在有限的速度和温度下和的屏蔽距离。根据上述分析，我们推断，在有限的速度和温度下，和比更稳定。

Moving doubly heavy baryon in a strongly coupled plasma via holography*

Gauge/gravity duality is used to study the properties of the doubly heavy baryon at finite rapidity and temperature in heavy-ion collisions. We investigate the impact of rapidity on string breaking and screening of and compare these effects with the results for in detail. Computations reveal that the string-breaking distances of and are close in the confined state, and the effects of rapidity and temperature on the string breaking are not significant. An interesting result shows that cannot be determined at sufficiently high temperatures and rapidities. However, can exist under any conditions as long as the separation distance is sufficiently small. Furthermore, the screening distances of and are compared at finite rapidity and temperature. Based on the above analysis, we infer that is more stable than at finite rapidity and temperature.
