“…In section 2.3 we have already mentioned some: gauge theories of gravity allow for more generalized Lagrangians, the inclusion of spinning matter as well as the possibility of Yang-Mills-like approaches. Scientists welcome at least some of these features for their unifying potential, which has led Liu (2001) to investigate carefully the pros and cons of already accomplished as well as proposed unification programmes. We are at this point less interested in giving a formal, possibly dogmatic list of criteria to be met by a scientific description in order to deserve being called unifying.…”

“…again Earman 2001). However, for studying the Yang-Mills theories of the standard model Lagrangian methods are at least equally important, but so far only few studies in the philosophy of science have dealt with them (Liu 2001 is a notable exception). In the present work we will be focussing on Yang-Mills-like gauge theoretic formulations of gravity.…”

Abstract. Four empirically equivalent versions of general relativity, namely standard GR, Lorentz-invariant gravitational theory, and the gravitational gauge theories of the Lorentz and translation groups, are investigated in the form of a case study for theory underdetermination. The various ontological indeterminacies (both underdetermination and inscrutability of reference) inherent in gravitational theories are analyzed in a detailed comparative study. The concept of practical underdetermination is proposed, followed by a discussion of its adequacy to describe scientific progress.

“…The two primary problems faced by BSM searches presently are the lack of reliable theoretical guidance and the lack of any discrepancies between SM predictions and collider data. One might think that these circumstances together suggest that BSM physics is a bit of a will-o'-the-wisp, but there are many reasons (of varying strength) to expect that there is physics beyond the SM, including the existence of dark matter (Zinkernagel 2002;Smeenk 2013), naturalness and the hierarchy problem (Giudice 2008;Grinbaum 2012;Williams 2015), and unification (Maudlin 1996;Wayne 1996;Morrison 2000;Li 2003). There are various proposals for solving these problems, the most promicontext depends on more nebulous, often implicit ideas like a metaphysical or theoretical core.…”

We introduce a novel point of view on the "models as mediators" framework in order to emphasize certain important epistemological questions about models in science which have so far been little investigated. To illustrate how this perspective can help answer these kinds of questions, we explore the use of simplified models in high energy physics research beyond the Standard Model. We show in detail how the construction of simplified models is grounded in the need to mitigate pressing epistemic problems concerning the uncertainty inherent in the present theoretical and experimental contexts.

Holism and structuralism in U(1) gauge theory

After decades of neglect philosophers of physics have discovered gauge theories-arguably the paradigm of modern field physics-as a genuine topic for foundational and philosophical research. Incidentally, in the last couple of years interest from the philosophy of physics in structural realism-in the eyes of its proponents the best suited realist position towards modern physics-has also raised. This paper tries to connect both topics and aims to show that structural realism gains further credence from an ontological analysis of gauge theories-in particular U (1) gauge theory. In the first part of the paper the framework of fiber bundle gauge theories is briefly presented and the interpretation of local gauge symmetry will be examined. In the second part, an ontological underdetermination of gauge theories is carved out by considering the various kinds of non-locality involved in such typical effects as the Aharonov-Bohm effect. The analysis shows that the peculiar form of non-separability figuring in gauge theories is a variant of spatiotemporal holism and can be distinguished from quantum theoretic holism. In the last part of the paper the arguments for a gauge theoretic support of structural realism are laid out and discussed.
