Welcome to EXCESS22@IDM, a satellite workshop of the IDM 2022 conference!

This is the 3rd iteration of the EXCESS workshop. The workshop was initiated in 2021 to discuss sharply rising low energy event rates observed by various rare event search experiments. While the first two iterations discussed observations and interpretations of the excesses, this event will focus on:

  • Updates from experiments (excess data, hypothesis tests, etc.)
  • Individual contributions (excess interpretations, proposed tests, etc.)
  • Outreach to entire dark matter community

While some talks will be by invitation, we also encourage everyone to submit an abstract with your individual work on the low energy excess signals.

The event is scheduled as a satellite meeting within the IDM conference, however, participation in the conference is no requirement to attend the workshop. Also talks by people who's work is not focused on dark matter are encouraged!


This workshop will be held in-person in Vienna, the location of the IDM 2022 conference: the Faculty of Electrical Engineering and Information Technology of the Technical University Vienna (TU Wien). On the workshop date, the path from the entrance of the building to the workshop location will be marked. For further information, see https://indico.cern.ch/event/922783/page/20348-venue
