We show that BLG-ABJM type of theories, discovered in the context of the AdS/CFT correspondence, generates gauge propagators with the complex pole structure prescribed by the Gribov scenario for confinement, which was developed in the context of Yang-Mills theories. This structure, known as i-particles in Gribov-Zwanziger theories, effectively allows the definition of composite operators with a positive Kallen-Lehmann spectral representation for their two-point functions. Therefore, these operators satisfy the criteria to describe glueball condensates. We calculate the (first-order) contribution to the two-point function of the gauge invariant condensate in the ABJM framework. We show that the correlator can be interpreted as a physical composite particle state in terms of the Kallen-Lehmann representation.

复陈-西蒙斯和 Gribov 禁闭情景

我们展示了在 AdS/CFT 对应关系中发现的 BLG-ABJM 类型的理论,生成具有 Gribov 限制场景规定的复杂极点结构的规范传播子,这是在 Yang-Mills 理论的背景下开发的。这种结构在 Gribov-Zwanziger 理论中被称为 i 粒子,有效地允许定义复合算子,其两点函数具有正 Kallen-Lehmann 谱表示。因此,这些算子满足描述胶球冷凝物的标准。我们计算了 ABJM 框架中规范不变凝聚的两点函数的(一阶)贡献。我们表明,根据 Kallen-Lehmann 表示,相关器可以解释为物理复合粒子状态。
