Abstract

One of the most important problems in Astrophysics and may be even in science today is that of the nature of the Dark Matter. There is a wide consensus[l] that at least 90% of the mass in the Universe does not shine. It is only detected through its gravitational interaction. The nature of this dark matter however is the subject of an intense debate[2]. The traditional view that it is made out of baryons[3] encounters significant difficulties with primordial nucleosynthesis[4], the absence of any electromagnetic radiation[5], and the conventional mechanisms of galaxy formation[6]. On the other hand, it is quite natural in many particle physics models to expect non-baryonic particles to be produced in the hot early universe, and to have today a density high enough to explain the observed Dark Matter. In this review, we summarize the experimental constraints on this scenario[7].
