内容概要

  The last thirty years have seen an enormous advance in our understanding of the microscopic world. We now have a convincing picture of the fundamental struc-ture of observable matter in terms of certain point-like elementary particles. We also have a comprehensive theory describing the behaviour of and the forces between these elementary particles, which we believe provides a complete and correct description of nearly all non-gravitational physics.  Matter, so it seems, consists of just two types of elementary particles: quarks and leptons. These are the fundamental building blocks of the material world, out of which we ourselves are made. The theory describ-ing the microscopic behaviour of these particles has,over the past decade or so, become known as the 'Standard Model', providing as it does an accurate account of the force of electromagnetism, the weak nuclear force (responsible for radioactive decay), and the strong nuclear force (which holds atomic nuclei together). The Standard Model has been remarkably successful; upuntil a year or two ago all experimental tests have verified the detailed predictions of the theory.  The Standard Model is based on the principle of 'gauge symmetry', which asserts that the properties and interactions of elementary particles are governed by certain fundamental symmetries related to familiar conservation laws.

章节摘录

版权页:插图:In order to understand the weak interaction in greater depth, we need to first delve further into the properties of relativistic fermions. In Section 4.2,we Jeamt that relativistic fermions are described by two-component spinors (with another two-component spinor for the antiparticle). In the Newtonian limit,when fermions move slowly, these two components can be interpreted as the two spin states of the fermion: the fermion can either be spin-up or spin-down. However,when the fermions are moving close to the speed of light, the notion of spin is no longer so useful and we need a new way in which to classify the two fermion states. In turns out that there are two useful ways to do this. The first, which is closely related to spin, is to define the helicity as the component of the fermion's spin in the direction of motion of the fermion. The spin can either be aligned with or against the momentum, and the fermion is referred to as being in the helicity-plus or helicity-minus state respectively.

  •   这本书全面的介绍了粒子物理及其相关概念,适合初学者
  •   有助于我们了解有关粒子物理的知识,但需要一定的英语知识
  •   基础入门书,读着比较轻松,当然也很有意思。
  •   降价买的,很值
  •   这本书是介绍性的,没有太多的公式,和复杂的计算,文字为主,适合初学者,尤其不了解的人。
  •   入门的好东西 告诉你啥是啥
  •   不错的介绍书,这学期我要学粒子物理,先买来看看。
  •   这书就是一科普书
  •   书很破,书皮都磨了好多,不喜欢
  •   送货很快,纸张不错,印得很清楚。粒子物理发展很快,这本书的原版(第三版)是06年出版的,内容应该是比较新的。正如书名所言,它只是对简单介绍了粒子物理的各个概念,没有任何数学推导。但这本书不是一般的科普书,而是针对有一定物理基础的人("An Introduction for Scientists")。如果你想对粒子物理又一个基本的了解,又不想被高深的理论挡在门外,不妨看看这本书。
  •   语言易懂,概念很清晰,跟我以前学习的总结很有共鸣;缺点是,嘿嘿,太浅易简略了吧,没公式,适合大三大四的学弟妹们看
