标量-物质-胶子相互作用
Scalar-matter-gluon interaction
摘要：
对规范理论的完全非微扰处理，需要包括与规范场同等地位的物质场。标量物质可以作为一般物质的角色模型，因为许多问题，例如禁闭，可以在不涉及特定洛伦兹结构的情况下提出。由于它们的结构相当简单，它们也有助于开发方法。描述规范理论的一种可能的方法是基于关联函数。在简单讨论了这种方法的基本原理后，我们用格点规范理论分析了胶子与猝灭的基本标量和伴随标量的相互作用。在最小朗道规范下，确定了有质量和无质量伴随标量和基本标量的两点和三点关联函数。这一发现与标量仅受胶子相互作用的轻微影响的可能性一致。的结果进行了简要的比较与动态，大规模标量，在限制区域相比，淬火的情况下，没有显着的变化。
英文摘要：
A full non-perturbative treatment of gauge theories requires to include matter fields on equal footing with the gauge fields. Scalar matter can act as a role model for generic matter, as many questions, e.g. confinement, can be posed without referring to a particular Lorentz structure. Due to their rather simple structure they are also useful to develop methods. One possible way to describe gauge theories beyond perturbation theory is based on correlation functions. After a short discussion of the setup, lattice gauge theory is used to analyze the interaction of gluons with quenched fundamental and adjoint scalars. Both the two-point and three-point correlation functions for massive and massless adjoint and fundamental scalars will be determined, in minimal Landau gauge. The findings are in agreement with the possibility that scalars are only slightly affected by the interaction with gluons. The results are compared briefly with dynamical, massive scalars, showing no significant changes in the confinement region compared to the quenched case.
