味物理与晶格量子色动力学

Flavor physics and lattice quantum chromodynamics

Laurent Lellouch

摘要:

本课程首先介绍标准模型,它被视为一种有效场论。实验和理论上的限制,在新物理的能量尺度可以出现,以及目前的限制夸克味参数,进行了审查。描述了格点量子色动力学在获得这些约束中的作用。第二部分致力于解释夸克味混合和CP破坏的Cabibbo-Kobayashi-Maskawa机制,并详细介绍其最显著的特征。第三部分致力于研究K -> pi pi衰变。它包括通过K^0- \bar K^0混合的间接CP破坏、ΔI=1/2规则和直接CP破坏的讨论。它提出了一些格点量子色动力学工具,需要从头描述这些现象。

英文摘要:

The course begins with an introduction to the Standard Model, viewed as an effective field theory. Experimental and theoretical limits on the energy scales at which New Physics can appear, as well as current constraints on quark flavor parameters, are reviewed. The role of lattice QCD in obtaining these constraints is described. A second section is devoted to explaining the Cabibbo-Kobayashi-Maskawa mechanism for quark flavor mixing and CP violation, and to detailing its most salient features. The third section is dedicated to the study of K -> pi pi decays. It comprises discussions of indirect CP violation through K^0-\bar K^0 mixing, of the ΔI=1/2 rule and of direct CP violation. It presents some of the lattice QCD tools required to describe these phenomena ab initio.
