粲偶素离解温度的相对论修正

Relativistic Correction to Charmonium Dissociation Temperature

Xingyu Guo, Shuzhe Shi, Pengfei Zhuang

摘要:

通过求解一对重夸克的协变相对论性薛定谔方程,得到了有限温度下夸克偶素基态和激发态的波函数。当中心势在自由能和内能之间变化时,由系统的无穷大或零结合能决定的$J/ψ$离解温度比非相对论计算的要高$7%-13%$.

英文摘要:

By solving the covariant relativistic Schrödinger equations for a pair of heavy quarks, we obtained the wave functions for the ground and excited quarkonium states at finite temperature. In comparison with the non-relativistic calculation, the $J/ψ$ dissociation temperature determined by the infinity size or zero binding energy of the system increases $7%-13%$, when the central potential varies between the free energy and internal energy.
