Abstract According to the Standard Model of particle physics, some gauge transformations are physical symmetries. That is, they are mathematical transformations that relate representatives of distinct physical states of affairs. This is at odds with the standard philosophical position according to which gauge transformations are an eliminable redundancy in a gauge theory's representational framework. In this paper I defend the Standard Model's treatment of gauge from an objection due to Richard Healey. If we follow the Standard Model in taking some gauge transformations to be physical symmetries then we face the “strong CP problem”, but if we adopt the standard philosophical position on gauge then the strong CP problem dissolves. Healey offers this as a reason in favor of the standard philosophical view. However, as I argue here, following Healey's recommendation gives a theory that makes bad empirical predictions.

大规格转换和强大的CP问题

摘要根据粒子物理学的标准模型，一些规范变换是物理对称性。也就是说，它们是将不同物理状态的代表联系起来的数学转换。这与标准的哲学立场不一致，在规范的哲学立场上，规范的转换是规范理论的表示框架中可消除的冗余。在本文中，我为理查德·希利（Richard Healey）提出的反对意见辩护了标准模型对量规的处理。如果我们遵循标准模型将某些量规转换为物理对称性，那么我们将面临“强CP问题”，但是如果我们在量规上采用标准哲学立场，那么强CP问题就将解决。希利将其作为支持标准哲学观点的一个理由。但是，正如我在这里所说的，
