含瞬子的<A^2>凝聚体的二分量图象

A two-component picture of the <A^2> condensate with instantons

David Vercauteren, Henri Verschelde

摘要:

本文研究了非阿贝尔规范理论中<A^2>凝聚与瞬子的相互作用。因此,我们使用局部复合算子的形式,与该凝聚的真空期望值可以解析计算。我们首先利用稀气体近似,部分地解决了瞬子物理的红外问题。然而,为了找到定量的结果,我们转向瞬子液体模型,在那里我们发现对凝结的不同贡献是如何加起来的。

英文摘要:

We study the interplay between the <A^2> condensate and instantons in non-Abelian gauge theory. Therefore we use the formalism of Local Composite Operators, with which the vacuum expectation value of this condensate can be analytically computed. We first use the dilute gas approximation and partially solve the infrared problem of instanton physics. In order to find quantitative results, however, we turn to an instanton liquid model, where we find how the different contributions to the condensate add up.
