Dark matter from gravitational particle production at reheating
Tommi Markkanen, Sami Nurmi
We show that curvature induced particle production at reheating generates adiabatic dark matter if there are non-minimally coupled spectator scalars weakly coupled to visible matte…
Lattice Calculation of the Decay of Primordial Higgs Condensate
Kari Enqvist, Sami Nurmi, Stanislav Rusak +1
We study the resonant decay of the primordial Standard Model Higgs condensate after inflation into gauge bosons on the lattice. We find that the non-Abelian interactions be…
Spacetime curvature and Higgs stability after inflation
Matti Herranen, Tommi Markkanen, Sami Nurmi +1
We investigate the dynamics of the Higgs field at the end of inflation in the minimal scenario consisting of an inflaton field coupled to the Standard Model only through the non-mi…
Inflationary Imprints on Dark Matter
Sami Nurmi, Tommi Tenkanen, Kimmo Tuominen
We show that dark matter abundance and the inflationary scale could be intimately related. Standard Model extensions with Higgs mediated couplings to new physics typically cont…
