量子场论与标准模型的结构

Quantum field theory and the structure of the Standard Model

José Ignacio Illana, Alejandro Jiménez Cano

摘要:

粒子物理学中的电弱相互作用和强相互作用的标准模型是一种量子场论。基本粒子不是不可分割的物质“碎片”,而是场的能量束,其性质和相互作用是对称性原理的结果。这些课堂讲稿提供了一个简单的介绍,从标准模型的基本组成部分:庞加莱对称性,规范不变性和自发对称性破缺。完整的拉格朗日推导详细和最相关的方面的电弱现象进行了讨论,特别强调的输入参数的确定和模型的一致性检查。建议做一些练习来固定主要思想。

英文摘要:

The Standard Model of the electroweak and strong interactions of particle physics is a quantum field theory. Elementary particles are not indivisible `pieces' of matter but energy bundles of fields, whose properties and interactions are a consequence of the principles of symmetry. These lecture notes provide a brief introduction to the construction of the Standard Model from its basic ingredients: Poincaré symmetry, gauge invariance and spontaneous symmetry breaking. The full Lagrangian is derived in detail and the most relevant aspects of the electroweak phenomenology are discussed with special emphasis on the determination of the input parameters and the consistency checks of the model. Some exercises are proposed to fix the main ideas.
