Description

The problem of missing mass in the Universe, at the scale of galaxies,
large-scale structures, and its global content, is a multi-faceted
enigma. In the cold dark matter scenario, one of the main candidate for the
non-baryonic particles, is the neutralino, the most stable of the
super-symmetric particles.
However, supersymmetry does not appear as expected in the LHC
experiments at CERN. Many other models have blossomed in recent years,
we will describe some alternatives such as axions, sterile neutrinos,
or modified gravity.
