We show that within the inverse seesaw mechanism for generating neutrino masses minimal supergravity naturally provides sneutrino as the lightest superparticle. We also demonstrate that such schemes naturally reconcile the small neutrino masses with the correct relic sneutrino dark matter abundance and accessible direct detection rates in nuclear recoil experiments. This way inverse seesaw minimal supergravity offers a common solution to the generation of the neutrino mass and to the origin of dark matter.

Abstract
We show that within the inverse seesaw mechanism for generating neutrino masses minimal supergravity naturally provides sneutrino as the lightest superparticle. We also demonstrate that such schemes naturally reconcile the small neutrino masses with the correct relic sneutrino dark matter abundance and accessible direct detection rates in nuclear recoil experiments. This way inverse seesaw minimal supergravity offers a common solution to the generation of the neutrino mass and to the origin of dark matter.File in questo prodotto:
