Sketching the inflaton potential
, 2002 Based on solutions of the Stewart-Lyth inverse problem it is argued that in the CMB data analysis the parametrization of the primordial spectra from inflation must include the `running' of both, scalar and tensorial, spectral indices if information beyond the exponential potential model is wanted to be detected.

Post-inflationary leptogenesis and dark matter production: metric versus Palatini formalism
Journal of High Energy PhysicsWe investigate production of non-thermal dark matter particles and heavy sterile neutrinos from inflaton during the reheating era, which is preceded by a slow-roll inflationary epoch with a quartic potential and non-minimal coupling (ξ) between inflaton ...
