Cosmological implications of primordial vector fields
A vector curvaton model for a massive Abelian vector field with a Maxwell type kinetic term is presented and analysed. The model does not suffer from instabilities such as ghosts. A scale-invariant spectrum of superhorizon perturbations can be generated if the mass and kinetic function of the vector...
