Self-interacting dark matter
Encyclopedia
In astrophysics
self-interacting dark matter is a hypothetical form of dark matter
consisting of particles with strong self-interactions. This type of dark matter was postulated to resolve a number of conflicts between observations and simulations on the galactic scale and smaller.
Self-interacting dark matter has also been postulated as an explanation for the DAMA
annual modulation signal.

Dark matter
In astronomy and cosmology, dark matter is matter that neither emits nor scatters light or other electromagnetic radiation, and so cannot be directly detected via optical or radio astronomy...

DAMA/NaI
The DAMA/NaI experiment was designed to detect dark matter using the direct detection technique. It was located at the Laboratori Nazionali del Gran Sasso in Italy and collected data during the period 1996-2002...
