Spacetime curvature and the Higgs stability during inflation.
TL;DR: The standard model Higgs effective potential is computed including UV-induced curvature corrections at one-loop level and it is found that for a high inflationary scale a large curvature mass is generated due to renormalization group running of nonminimal coupling ξ.

Spacetime Curvature and Higgs Stability after Inflation.
Matti Herranen,Tommi Markkanen,Tommi Markkanen,Sami Nurmi,Sami Nurmi,Arttu Rajantie,Arttu Rajantie +6 more
TL;DR: It is found that for ξ≳1, rapidly changing spacetime curvature at the end of inflation leads to significant production of Higgs particles, potentially triggering a transition to a negative-energy Planck scale vacuum state and causing an immediate collapse of the Universe.

Lattice Calculation of Non-Gaussian Density Perturbations from the Massless Preheating Inflationary Model
Alex Chambers,Arttu Rajantie +1 more
TL;DR: In this article, the authors show that if light scalar fields are present at the end of inflation, their nonequilibrium dynamics such as parametric resonance or a phase transition can produce non-Gaussian density perturbations.
