大N时的矩形威尔逊圈

Rectangular Wilson Loops at Large N

Robert Lohmayer, Herbert Neuberger

摘要:

本文是关于规范群为SU(N)的四维欧氏空间中的纯杨-米尔斯理论。我们研究了大N时晶格上的矩形涂抹威尔逊圈,并且在它们的本征值密度中相对接近大N的转变点。我们表明,弦张力可以从这些回路,但它们的形状依赖不同的有效弦论的渐近预测。

英文摘要:

This work is about pure Yang-Mills theory in four Euclidean dimensions with gauge group SU(N). We study rectangular smeared Wilson loops on the lattice at large N and relatively close to the large-N transition point in their eigenvalue density. We show that the string tension can be extracted from these loops but their dependence on shape differs from the asymptotic prediction of effective string theory.
