论文摘要

在本文中,我们介绍了有关强子物理和QCD物质的动力全息QCD方法的简短概述。 The 5-dimensional dynamical holographic QCD model is constructed in the graviton-dilaton-scalar framework with the dilaton background field $Φ$ and the scalar field $X$ dual to the gluon condensate and the chiral condensate operator thus can represent the gluodynamics (linear confinement) and chiral dynamics (chiral symmetry breaking), respectively. DILATON背景场和标量场是第五维的函数,第五维度扮演了能量尺度的作用,这样,DHQCD模型可以类似于从紫外线(UV)到红外(IR)的重新归一化组。通过求解爱因斯坦方程,IR处的度量结构会因真空中的非扰动Gluon凝结和手性凝结而自动变形。我们回顾了有关强体光谱的结果,包括粘合球光谱,光/重的介子光谱以及QCD相变,以及动力全息QCD模型框架中的热力学和传输性能。

In this paper we present a short overview on the dynamical holographic QCD method for hadron physics and QCD matter. The 5-dimensional dynamical holographic QCD model is constructed in the graviton-dilaton-scalar framework with the dilaton background field $Φ$ and the scalar field $X$ dual to the gluon condensate and the chiral condensate operator thus can represent the gluodynamics (linear confinement) and chiral dynamics (chiral symmetry breaking), respectively. The dilaton background field and the scalar field are a function of the 5th dimension, which plays the role of the energy scale, in this way, the DhQCD model can resemble the renormalization group from ultraviolet (UV) to infrared (IR). By solving the Einstein equation, the metric structure at IR is automatically deformed by the nonperturbative gluon condensation and chiral condensation in the vacuum. We review the results on the hadron spectra including the glueball spectra, the light/heavy meson spectra, as well as on QCD phase transitions, and thermodynamical as well as transport properties in the framework of the dynamical holographic QCD model.
