Description

The workshop on ultralight dark matter searches Dark Matter: A Light Move aims to explore and gather ideas about searching directly (and to a lesser extent indirectly) for Dark Matter candidates with sub-eV masses, most prominently the axion and other weakly interacting light particles (WISPs).

The workshop’s aim is to provide a platform for elaborate discussions and foster collaborations and new experiments. We therefore foresee short presentations + up to 30min discussion time. All speakers are therefore highly encouraged to include in their talk also their own questions to the community and use the opportunity to discuss also "unfinished" ideas with colleagues from different disciplines.

During this two-day workshop, we foresee

  • a brief theory overview for WISPY DM,
  • general evidence for DM and peculiar features of WISPy DM, astrophysical evidence,
  • existing axion DM setups,
  • prospects of WISP DM setups (cavities, dish-searches...),
  • relevant experimental techniques: magnetic challenges, detectors.

Confirmed speakers include already:

  • Andrei Lobanov (MPIfR)
  • Igor Irastorza (Zaragoza)
  • Michael Betz (CERN)
  • Axel Lindner (DESY)
  • Joerg Jaeckel (Heidelberg)
  • Javier Redondo (LMU Munich)
