建立模型的系统方法

A systematic approach to model building

Damien P. George

摘要:

我们概述了一个新的,系统的方式来构建和分析场论,其中所有可能的连续对称性的一个给定的模型是使用李点对称性的方法。如果模型具有自由参数,并且这些参数中的任何一个之间的关系产生增强的对称性,那么所有这些关系都被找到,以及由此产生的对称群。我们将讨论如何将该方法应用于标准模型和超越,直接寻找一个更具预测性的场论。该方法处理紧和非紧连续群,自发破缺对称性,也适用于广义相对论。

英文摘要:

We outline a new, systematic way of constructing and analysing field theories, where all possible continuous symmetries of a given model are derived using the method of Lie point symmetries. If the model has free parameters, and relationships amongst any of these parameters yields an enhanced symmetry, then all such relationships are found, along with the resulting symmetry group. We discuss how the method can be applied to the standard model and beyond, to direct the search for a more predictive field theory. The method handles compact and non-compact continuous groups, spontaneously broken symmetries, and is also applicable to general relativity.
