Self-Interacting Dark Matter: Models, Simulations and Signals

The lack of signals in terrestrial searches for dark matter indicates that dark matter may reside in its own sector and carry its own forces. The existence of such a dark sector has profound implications for cosmic structure formation, as it generically predicts that dark matter has self-interactions. Recent studies show that gravothermal collapse, a characteristic feature of dark matter self-interactions, can occur in viable Self-Interacting Dark Matter (SIDM) models, which open up exciting possibilities for discovery. SIDM may also provide a solution to the too-big-to-fail problem and the diversity problem of field galaxies, which are long-standing puzzles in astrophysics.

This workshop will focus the discussions on SIDM models, simulations, and astronomical signals, as well as the current status of the small-scale structure issues. It will provide a rare opportunity for the experts from different fields to discuss the latest results, identify targets for a breakthrough, and exchange ideas for future progress in this promising research area.

The workshop on Self-Interacting Dark Matter: Models, Simulations and Signals aims to bring together leading experts from diverse research backgrounds, including particle physics model building, numerical simulations, and astrophysical observations, all working in the beautiful setting of the medieval town of Pollica in Southwestern Italy (Cilento region). The workshop is scheduled for the dates of 19th to 30th of June 2023.

Location: The workshop will take place in Castello dei Principi Capano, see the map for also nearby restaurant suggestions.
