Abstract
In this paper, we employ gauge/gravity duality to investigate the string breaking and melting of doubly-heavy tetraquark that includes two heavy quarks and two light antiquarks in a holographic model at finite temperature. Firstly, we investigate four configurations of in the confined phase and consider different separation distances of the heavy quarks at varying temperatures. At high temperature, melts at certain distances and the confined quarks are released. As the temperature continues to increase, some configurations of doubly-heavy tetraquark can not exist. Furthermore, we investigate three decay modes of and compare the potential energy of with that of at finite temperature .
