摘要：
The right-handed sneutrino is a viable WIMP dark matter candidate within the context of the Next-to-MSSM. This is possible through the inclusion of a new singlet superfield with direct coupling to the singlet Higgs. I will review here the main details of this construction, together with the properties of the right-handed sneutrino, including its annihilation channels and direct detection prospects. Sneutrinos within a mass-range of 5-200 GeV can reproduce the correct dark matter relic abundance while not being excluded by current direct searches, and for natural values of the input parameters. Some interesting features regarding collider phenomenology are also pointed out.
