Resolving primordial physics through correlated signatures
Kari Enqvist, David J. Mulryne, Sami Nurmi
We discuss correlations among spectral observables as a new tool for differentiating between models for the primordial perturbation. We show that if generated in the isocurvature s…
Spacetime curvature and the Higgs stability during inflation
Matti Herranen, Tommi Markkanen, Sami Nurmi +1
It has been claimed that the electroweak vacuum may be unstable during inflation due to large fluctuations of order in case of a high inflationary scale as suggested by BICEP2.…
Standard Model with a real singlet scalar and inflation
Kari Enqvist, Sami Nurmi, Tommi Tenkanen +1
We study the post-inflationary dynamics of the Standard Model Higgs and a real singlet scalar , coupled together through a renormalizable coupling , in a sym…
Non-Abelian dynamics in the resonant decay of the Higgs after inflation
Kari Enqvist, Sami Nurmi, Stanislav Rusak
We study the resonant decay of the Higgs condensate into weak gauge bosons after inflation and estimate the corrections arising from the non-Abelian self-interactions of the gauge…
