Doubly-heavy tetraquark at finite temperature in a holographic model
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, four different configurations of $${{\textrm{QQ}}}\bar{{\te...

| description | 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, four different configurations of $${{\textrm{QQ}}}\bar{{\textrm{q}}}\bar{{\textrm{q}}}$$ QQ q ¯ q ¯ are studied at different separation distances of the heavy quarks at finite temperatures. At high temperature, $${{\textrm{QQ}}}\bar{{\textrm{q}}}\bar{{\textrm{q}}}$$ QQ q ¯ q ¯ will melt at certain distances and the screening distance has been given for different temperatures. As the temperature continues to increase, some configurations of doubly-heavy tetraquark can not exist. Furthermore, we investigate three decay modes of $${{\textrm{QQ}}}\bar{{\textrm{q}}}\bar{{\textrm{q}}}$$ QQ q ¯ q ¯ and compare the potential energy of $${{\textrm{QQ}}}\bar{{\textrm{q}}}\bar{{\textrm{q}}}$$ QQ q ¯ q ¯ with that of $${\textrm{QQq}}$$ QQq at finite temperature. |
