解禁闭温度的全息估算

Holographic Estimates of the Deconfinement Temperature

S. S. Afonin, A. D. Katanaeva

摘要:

在自下而上的全息QCD方法的框架内的解除禁闭温度Tc的自洽估计的问题进行了审查。结果表明,标准软壁模型给出了Tc的平面gluodynamics在260 MeV左右,在一个很好的协议与晶格数据。软壁模型的扩展调整为现实的介子谱的描述,结果在广泛的预测。这种不确定性与径向激发介子的实验信息不足有关。

英文摘要:

The problem of self-consistent estimates of the deconfinement temperature Tc in the framework of the bottom-up holographic approach to QCD is scrutinized. It is shown that the standard soft wall model gives Tc for planar gluodynamics around 260 MeV in a good agreement with the lattice data. The extensions of soft wall model adjusted for descriptions of realistic meson spectra result in a broad range of predictions. This uncertainty is related with a poor experimental information on the radially excited mesons.
