  1. Title: Constraining Curvatonic Reheating. ... The information gained about reheating is also quantified and it is found that it remains modest in plateau inflation (though still larger than in the single-field version of the model) but can become substantial in quartic inflation. The role played by the vev of the additional scalar field at the ...
  2. Deriving such a relationship for concrete reheating models is therefore an important, although often laborious, task. Let us also notice that since the dependence of in ationary predictions on the reheating history is now of the same order as the accuracy of the data itself, di erent prescriptions for the reheating dynamics give rise to substan-

    Constraining curvatonic reheating. Robert Hardwick, Vincent Vennin, Kazuya Koyama, David Wands. ... We find that, compared to the single-field case, lower values of the energy density at the end of inflation and of the reheating temperature are preferred when an additional scalar field is introduced. For instance, if inflation is driven by a ...

  6. We derive the first systematic observational constraints on reheating in models of inflation where an additional light scalar field contributes to primordial density perturbations and affects the expansion history during reheating. This encompasses the original curvaton model but also covers a larger class of scenarios. We find that, compared to the single-field case, lower values of the ...

    Key takeaway: 'An additional light scalar field in inflation models leads to lower energy density and reheating temperature values, with modest reheating in plateau inflation and substantial reheating in quartic inflation.' ...
