Axino Mass

Abstract

The mass of the axino is computed in realistic supersymmetric extensions of the standard model. It is found to be strongly model dependent and can be as small as a few keV but also as large as the gravitino mass. Estimates of this mass can only be believed once a careful analysis of the scalar potential has been performed.
