Thermal blocking of preheating

Rose Lerner, Anders Tranberg

The parametric resonance responsible for preheating after inflation will end when self-interactions of the resonating field and interactions of this field with secondary degrees of…

Quantifying the 'naturalness' of the curvaton model

Rose N. Lerner, Scott Melville

We investigate the probability of obtaining an observable curvature perturbation, using as an example the minimal curvaton-higgs (MCH) model. We determine 'probably observable' and…

The minimal curvaton-higgs model

Kari Enqvist, Rose N. Lerner, Tomo Takahashi

We present the first full study of the minimal curvaton-higgs (MCH) model, which is a minimal interpretation of the curvaton scenario with one real scalar coupled to the standard m…

Reheating dynamics affects non-perturbative decay of spectator fields

Kari Enqvist, Rose N. Lerner, Stanislav Rusak

The behaviour of oscillating scalar spectator fields after inflation depends on the thermal background produced by inflaton decay. Resonant decay of the spectator is often blocked…

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…
