“…Measurements, for example the high Q 2 higgs production, provide constraints on the values for some Wilson coefficients, or -in case a significant deviation -their values. As discussed in Bechtle et al (2022), the SM-EFT has no representational meaning but, in the words of Contino et al (2013), "[parametrizes] our ignorance". 33 Knowing these constraints has important implications for the strategy of further measurements -comparable to conceptualization of an observed signal.…”

“…It is thus not only that nothing has been found, but basic concepts for predicting BSM physics are perceived to have been turned down. Particle physicists are moving more and more to searches that are 'model independent' 9 and expectations that experiments will guide theory (Bechtle et al, 2022). This is underlined in a survey among particle physicists.…”

Along three measurements at the Large Hadron Collider (LHC), a high energy particle accelerator, we analyze procedures and consequences of exploratory experimentation (EE). While all of these measurements fulfill the requirements of EE: probing new parameter spaces, being void of a target theory and applying a broad range of experimental methods, we identify epistemic differences and suggest a classification of EE. We distinguish classes of EE according to their respective goals: the exploration where an established global theory cannot provide the details of a local phenomenon, exploration of an astonishing discovery and exploration to find a new entity. We find that these classes also differ with respect to the existence of an identifiable target and their impact on the background theory. The characteristics distinguish EE from other kinds of experimentation, even though these different kinds have not yet been systematically studied. The formal rigor and precision of LHC physics facilitates to analyze concept formation in its early state. In particular we emphasize the importance for nil–results for conceptualization and argue that conceptualization can also be achieved from nil–results only.

Open systems across scales

The view that our best current physics deals with effective systems has gained philosophical traction in the last two decades. A similar view about open systems has also been picking up steam in recent years. Yet little has been said about how the concepts of effective and open systems relate to each other despite their apparent kinship—both indeed seem at first sight to presuppose that the system in question is somehow incomplete. In this paper, I distinguish between two concepts of effectiveness and openness in quantum field theory, which provides a remarkably well-developed theoretical framework to make a first stab at the matter, and argue that on both counts, every realistic effective system in this context is also open. I conclude by highlighting how the discussion opens novel avenues for thinking of systems as open across scales.
