Abstract
The direct detection of neutralino dark matter is analysed in the framework of the Next‐to‐Minimal Supersymmetric Standard Model. After performing a detailed analysis of the parameter space, taking into account all the available constraints from LEP, the neutralino‐nucleon cross section is computed. Sizable values for the detection cross section, within the reach of dark matter detectors, are attainable in this scenario, due to the exchange of very light Higgses with mh10 ≲ 70 GeV. These have a significant singlet composition, thus escaping detection and being in agreement with accelerator data. The lightest neutralino exhibits a large singlino‐Higgsino composition, and a mass in the range 50 ≲ mχ̃10 ≲ 100 GeV.
