具有全息势的重夸克偶素态

Heavy Quarkonium States with the Holographic Potential

Defu Hou, Hai-cang Ren

摘要:

利用全息原理所隐含的重夸克势研究了夸克-胶子等离子体中的夸克偶素态。考虑了vanila AdS-Schwarzschild度规和红外截止度规。解离温度通过求解势模型的薛定谔方程来计算。在AdS-Schwarzschild度规与IR截止的情况下,发现$J/ψ$和$Υ$与U-反电势的解离温度与晶格结果在2倍之内一致。

英文摘要:

The quarkonium states in a quark-gluon plasma is examined with the heavy quark potential implied by the holographic principle. Both the vanila AdS-Schwarzschild metric and the one with an infrared cutoff are considered. The dissociation temperature is calculated by solving the Schrö dinger equation of the potential model. In the case of the AdS-Schwarzschild metric with a IR cutoff, the dissociation temperatures for $J/ψ$ and $Υ$ with the U-ansatz of the potential are found to agree with the lattice results within a factor of two.
