Abstract The current state of particle physics is conflicting. One has a marvellously working theory, the Standard Model, that leaves many questions open. This tension has led to a variegated landscape of models of physics beyond the Standard Model that is guided by epistemic and pragmatic values of model preference. Whereas these preferences are shared by experimentalists and theorists, their use of models within research practice differs. Experimentalists focus on event signatures that have many-to-many relations to models. We argue that physicists’ three-pronged approach distinguishing raw data, signatures, and models resembles the analysis of Bogen and Woodward, establishing the autonomy of phenomena. Using signatures opens the door for explorative experimentation, which becomes crucial for managing the uncertainty about the direction of particle physics that has emerged after the discovery of the Higgs boson.

基本粒子物理学中的模型景观和事件签名

摘要粒子物理学的现状是相互矛盾的。一个具有奇妙工作原理的标准模型,它留下了许多问题。这种张力导致了超出标准模型的各种物理模型格局,而模型模型是由模型偏好的认知和实用价值指导的。尽管这些偏好是实验家和理论家所共有的,但是它们在研究实践中对模型的使用却有所不同。实验学家专注于与模型具有多对多关系的事件签名。我们认为,物理学家区分原始数据,特征和模型的三管齐下的方法类似于对Bogen和Woodward的分析,从而建立了现象的自治性。使用签名打开了探索性实验的大门,
