向一年级学生讲授规范理论

Teaching gauge theory to first year students

Nils-Erik Bomark

摘要:

20世纪物理学最大的发现之一,在粒子物理学的内部圈子之外几乎闻所未闻。这就是规范理论,它是描述所有物理相互作用的基础,也是几乎所有新物理理论工作的指导原则。作为物理学家,我们有责任把这些知识传播给更广泛的受众吗?在这里,两个简单的规范理论模型,应该是可以理解的,没有任何高等数学或物理,它演示了如何使用它们来显示如何规范对称性被用来构建粒子物理学的标准模型。这也被用来描述我们需要希格斯场的真正原因。虽然这些概念是复杂和抽象的,但至少一年级的学生似乎可以理解主要思想。由于他们通常对前沿物理学非常感兴趣,他们确实很欣赏这种努力,并喜欢对现代粒子物理学的更详细的了解。这些结果无疑鼓励在这方面作出更多努力。

英文摘要:

One of the biggest revelations of 20th century physics, is virtually unheard of outside the inner circles of particle physics. This is the gauge theory, the foundation for how all physical interactions are described and a guiding principle for almost all work on new physics theories. Is it not our duty as physicists to try and spread this knowledge to a wider audience? Here, two simple gauge theory models are presented that should be understandable without any advanced mathematics or physics and it is demonstrated how they can be used to show how gauge symmetries are used to construct the standard model of particle physics. This is also used to describe the real reason we need the Higgs field. Though these concepts are complicated and abstract, it seems possible for at least first year students to understand the main ideas. Since they typically are very interested in cutting edge physics, they do appreciate the effort and enjoy the more detail insight into modern particle physics. These results are certainly encouraging more efforts in this direction.
