curvaton
  کورواتون   
kurvaton

Fr.: curvaton   

A hypothetical → scalar field that is used to explain the → primordial curvature perturbation in the Universe. It is generally supposed that the primordial perturbation originates during → inflation, from the → quantum fluctuation of the inflation field. The curvaton model is an attempt to account for the primordial perturbation by a completely different origin, namely the quantum fluctuation during inflation of a light scalar field which is not the assumed slowly-rolling inflation. In this model, the curvaton field is an energetically sub-dominant component during inflation. As the energy density of the Universe drops after inflation, the fraction of this component becomes significant. At this time the curvaton perturbation is converted into an adiabatic curvature perturbation of the Universe. The amplitude of the final perturbation, which should match observations, depends on both how long the curvaton oscillates before it decays, and on the shape of the potential. The first curvaton model was proposed by D. H. Lyth & D.Wands and in 2002 (Physics Letters B524).

From curvat-, from → curvature, + → -on. Although not related, the term curvaton exists in Fr. meaning "small curve" with variants curvatone, courbaton, and corbatone (A. Jal, 1848, Glossaire nautique).
