We discuss the relic abundance of the right-handed sneutrinos in the supersymmetric F{sub D}-term model of hybrid inflation. As well as providing a natural solution to the {mu}- and gravitino overabundance problems, the model offers the lightest right-handed sneutrino as a candidate for thermal dark matter. The F{sub D}-term model predicts a new quartic coupling of purely right-handed sneutrinos to the Higgs doublets that thermalizes the sneutrinos and makes them annihilate sufficiently fast to a level compatible with the current cosmic microwave background data. We discuss this scenario and identify favourable regions of the parameter space within mSUGRA.
