Non-Gaussian tail of the curvature perturbation in stochastic ultra-slow-roll inflation: implications for primordial black hole production
Daniel G. Figueroa, Sami Raatikainen, Syksy Rasanen +1
We consider quantum diffusion in ultra-slow-roll (USR) inflation. Using the formalism, we present the first stochastic calculation of the probability distribution $P(\mathcal{…
Critical point Higgs inflation in the Palatini formulation
Vera-Maria Enckell, Sami Nurmi, Syksy Rasanen +1
We study Higgs inflation in the Palatini formulation with the renormalisation group improved potential in the case when loop corrections generate a feature similar to an inflection…
Gravitational dark matter production in Palatini preheating
Alexandros Karam, Martti Raidal, Eemeli Tomberg
We study preheating in plateau inflation in the Palatini formulation of general relativity, in a special case that resembles Higgs inflation. It was previously shown that the oscil…
Initial conditions for plateau inflation: a case study
Tommi Tenkanen, Eemeli Tomberg
We study initial conditions for inflation in scenarios where the inflaton potential has a plateau shape. Such models are those most favored by Planck data and can be obtained in a…
