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.
