论文摘要
我们考虑了与Einstein-Dilaton系统耦合的改进的软壁广告/QCD模型，该模型提供了一种同时研究解剖和手性转变的方法。在爱因斯坦 - 迪拉顿 - 刻画系统中，已经详细研究了这两个过渡之间的相关性与代表模型风味部门物质真空的批量标量场。我们发现，尽管状态方程都可以与$δ= 2.5、3、3.5 $的两种晶格结果相匹配，但在手性转变中表现出diLaton双重操作员的缩放维度$δ$的影响，尽管状态方程式都可以匹配。在较小$β$的弱耦合情况下，状态方程和手性转变都表现出交叉行为，并随着$β$的增加而变成一阶相变。
We consider an improved soft-wall AdS/QCD model coupled to an Einstein-dilaton system, which offers a way to study the deconfining and chiral transitions simultaneously. The correlation between these two transitions has been investigated in detail in the Einstein-dilaton-scalar system with the bulk scalar field representing the vacuum of matters in the flavor sector of the model. We find that the effects of the scaling dimension $Δ$ of the dual operator of the dilaton manifest in chiral transitions, although the equation of state can all be matched with the two-flavor lattice results for $Δ=2.5, 3, 3.5$ in the decoupling case of $β=0$. In the weak-coupling case with smaller $β$, both the equation of state and the chiral transition exhibit a crossover behavior and turn into first-order phase transitions with the increase of $β$.
