形变$AdS_5$模型的重夸克势

Heavy quark potential from deformed $AdS_5$ models

Zi-qiang Zhang, De-fu Hou, Gang Chen

摘要:

本文研究了几种全息QCD模型中的重夸克势。在研究了Pirner-Galow模型和Andreev-Zakharov模型中的重夸克势后,我们将讨论推广到一般形变$AdS_5$情形.结果表明,对于所有的夸克-反夸克分离,所得到的势都是负定的,这与通常的重整化方案所得到的势不同。

英文摘要:

In this paper, we investigate the heavy quark potential in some holographic QCD models. The calculation relies on a modified renormalization scheme mentioned in a previous work of Albacete et al. After studying the heavy quark potential in Pirner-Galow model and Andreev-Zakharov model, we extend the discussion to a general deformed $AdS_5$ case. It is shown that the obtained potential is negative definite for all quark-antiquark separations, differs from that using the usual renormalization scheme.
