Call for Registration: Dark Matter & Modified Gravity Conference (6-8/02/2019, Aachen)

The Research Unit „Epistemology of the LHC“ invites students and other scholars in philosophy, history and sociology of physics/science, as well as in physics, to register for the conference „Dark Matter & Modified Gravity“, taking place from 6 to 8 February 2019 at RWTH Aachen University, Germany: www.lhc-epistemologie.uni-wuppertal.de/dm-mg

INTERDISCIPLINARY PERSPECTIVES ON THE UNDERDETERMINATION BETWEEN DARK MATTER & MODIFIED GRAVITY

Astrophysical and cosmological observations as well as explanatory gaps in the Standard Model of particle physics imply the existence of Dark Matter and/or a modification of our theory of space and time. A decision between the Dark Matter (DM) and Modified Gravity (MG) approaches is hampered by problems of underdetermination at different levels and of different kinds. The plethora of Dark Matter and Modified Gravity approaches, and the corresponding underdetermination, even in the light of the vast amount of relevant collider based and astrophysical observations, clearly illustrates the complexity of this scientific problem. On the other hand, the overlap of the collider and astrophysical domains may allow for reducing the underdetermination, thus leading to a simplification of the model landscape. One focus of this conference is Dark Matter searches at the Large Hadron Collider and the connection between LHC results and theories of gravity. We will address the question of different kinds of underdetermination, both in choosing between the two research programs of Dark Matter and Modified Gravity, and also in choosing between different models within each program. In particular, we aim to provide an assessment of the explanatory power and the explanatory gaps of the Dark Matter and Modified Gravity hypotheses, and the extent to which these might reduce the issues of underdetermination.

Research topics include, but are not limited to:

  • Is a strict conceptual distinction between DM and MG justified? How does this relate to the distinction between matter and spacetime?
  • What are the explanatory successes and failures of the DM research programme, and of the MG research programme? Which models of explanation are being employed by the respective programmes, and how do those relate?
  • Sociology of the DM-MG debate
  • How do data, constraints and explanations at the LHC, in astrophysics and cosmology relate? Could the LHC, in principle, confirm dark matter by itself?
  • Virtues and vices of simplified (dark matter) models. Do simplified models explain?
  • Hybrid models, fifth forces & exotic theories that are neither MG nor DM
  • Connections between dark energy and DM/MG
  • Novel predictions, fine-tuning and falsifiability
