Abtract In this paper, ‘novelty’ is explored through a recent historical episode from high energy experimental physics to offer an understanding of novelty as disruption. I call this the ‘750 GeV episode’, an episode where two Large Hadron Collider (LHC) experiments, CMS and ATLAS, each independently observed indications of a new resonance at approximately 750 GeV. With further data collection, the initial excess was determined to be a statistical fluctuation. The approach taken, in the analysis of interviews conducted with physicists who were involved in the ‘750 GeV episode’, is to consider novelty as a valued difference. Following this conceptually driven approach, disambiguate between several notions of novelty through the identification of varied differences. This disambiguation is achieved through exploring differences expressed in comparison to varied expressions of the standard model, and through exploring varied ‘types’ of difference (properties and entities) to introduce disruptive exploratory experimentation, a complementary understanding ‘exploratory experimentation’ (Elliott, 2007; Steinle, 1997, 2002). I show that the kinds of novelty framed as most valuable are those that violate expectations and are difficult to incorporate into the existing structures of knowledge. In such instances, disruption to the existing ontology or ways of knowing is valued. This positive appraisal of disruption, and contradiction over confirmation, is considered in the recent context of high-energy physics, where several physicists have claimed that there is a lack of promising directions for the future, or even that the field is in a ‘crisis’. I show that the role of disruption explains the differences between the differing notions of novelty. Furthermore, I show that the positive appraisal of disruption is based on forward looking assessments of future fertility, or heuristic appraisal (Nickles, 1989, 2006). Within the context of concerns of a lack of available promising future directions, disruption becomes a generator of alternative futures.

在大型强子对撞机中探索新颖性:破坏性实验的启发式评估

摘要在本文中,“高新”是通过高能实验物理学的最近历史故事来探索的,以提供对新颖性的理解,即破坏。我将其称为“ 750 GeV事件”,这是两个大型强子对撞机(LHC)实验(CMS和ATLAS)分别独立观察到在大约750 GeV处出现新共振的迹象的事件。随着进一步的数据收集,最初的超额被确定为统计波动。在对参与“ 750 GeV事件”的物理学家进行的采访分析中,所采取的方法是将新颖性视为重要差异。遵循这种概念驱动的方法,通过识别各种差异来消除几种新颖概念之间的歧义。这种歧义是通过探索与标准模型的各种表达方式相比所表达的差异,以及通过探索差异的“类型”(属性和实体)来引入破坏性探索性实验,一种补充性的理解“探索性实验”来实现的(Elliott,2007; 2007)。 Steinle,1997,2002)。我表明,最有价值的新颖事物是那些违反期望并且难以融入现有知识结构的事物。在这种情况下,对现有本体或已知方式的破坏是很重要的。在高能物理学的最新背景下,人们对这种对破坏和对确认的矛盾的积极评价被认为是其中的事,在此背景下,几位物理学家声称缺乏对未来的有希望的指导,甚至认为该领域处于“危机”中。我证明了破坏的作用解释了不同新颖性概念之间的差异。此外,我证明对中断的正面评价是基于对未来生育力的前瞻性评估或启发式评估(Nickles,1989,2006)。在缺乏可用的有前途的未来方向的担忧的背景下,破坏成为替代期货的产生者。
