Description
We study the minimal SUGRA phenomenology in the case of an
alternative seesaw mechanism for generating neutrino masses. Changes in
the neutrino sector lead to a modification of the supersymmetric
particle spectrum and the sneutrino naturally arises as the lightest
supersymmetric particle. The obtained sneutrino has a relic density
within the WMAP range and is compatible with present nuclear recoil
bounds.
