有限温度下限流管的有效弦描述

Effective string description of the confining flux tube at finite temperature

Michele Caselle

摘要:

在这篇综述中,在对纯规范理论中禁闭的有效弦论(EST)描述作了一般性介绍之后,我们讨论了EST随温度升高的行为。我们表明,作为解除禁闭点接近从下面,约束规范理论的几个普遍的功能,如比率$T_c/\sqrt{σ_0}$,线性增加的平方宽度的通量管与夸克间的距离,或温度依赖性的夸克间的潜力,可以准确地预测的有效字符串。此外,在解除禁闭点附近的EST行为原来是在很好的协议与预测的共形不变性或降维,从而进一步支持的有效性和EST方法的限制。

英文摘要:

In this review, after a general introduction to the effective string theory (EST) description of confinement in pure gauge theories, we discuss the behaviour of EST as the temperature is increased. We show that, as the deconfinement point is approached from below, several universal features of confining gauge theories, like the ratio $T_c/\sqrt{σ_0}$, the linear increase of the squared width of the flux tube with the interquark distance, or the Temperature dependence of the interquark potential, can be accurately predicted by the effective string. Moreover in the vicinity of the deconfinement point the EST behaviour turns out to be in good agreement with what predicted by conformal invariance or by dimensional reduction, thus further supporting the validity of and EST approach to confinement.
