Curvaton Decay by Resonant Production of the Standard Model Higgs
Kari Enqvist, Daniel G. Figueroa, Rose N. Lerner
We investigate in detail a model where the curvaton is coupled to the Standard Model higgs. Parametric resonance might be expected to cause a fast decay of the curvaton, so that it…
Electrically charged curvaton
Michela D'Onofrio, Rose N. Lerner, Arttu Rajantie
We consider the possibility that the primordial curvature perturbation was generated through the curvaton mechanism from a scalar field with an electric charge, or precisely the St…
Spectator field dynamics in de Sitter and curvaton initial conditions
Kari Enqvist, Rose N. Lerner, Olli Taanila +1
We investigate the stochastic behaviour of long wavelength modes of light spectator scalar fields during inflation. When starting from a classical field value, the probability dist…
