Scientific paper

The direct detection of neutralino dark matter in general supergravity theories with non-universal soft scalar and gaugino masses is reviewed. In particular, the neutralino-proton cross section is computed and compared with the sensitivities of dark matter detectors, taking into account the most recent experimental and astrophysical constraints, as well as those coming from charge and colour breaking minima. Gaugino and scalar non-universalities provide a large flexibility in the neutralino sector, and neutralinos close to the present detection limits are possible with a wide range of masses, from over 400 GeV to almost 10 GeV.
