Cosmological Aspects of Higgs Vacuum Metastability
Tommi Markkanen, Arttu Rajantie, Stephen Stopyra
The current central experimental values of the parameters of the Standard Model give rise to a striking conclusion: metastability of the electroweak vacuum is favoured over absolut…
Despicable Dark Relics: generated by gravity with unconstrained masses
Malcolm Fairbairn, Kimmo Kainulainen, Tommi Markkanen +1
We demonstrate the existence of a generic, efficient and purely gravitational channel producing a significant abundance of dark relics during reheating after the end of inflation.…
Dark energy as a remnant of inflation and electroweak symmetry breaking
Konstantinos Dimopoulos, Tommi Markkanen
It is shown that dark energy can be obtained from the interplay of the Higgs boson and the inflaton. A key element is the realization that electroweak symmetry breaking can trigger…
The 1-loop effective potential for the Standard Model in curved spacetime
Tommi Markkanen, Sami Nurmi, Arttu Rajantie +1
The renormalisation group improved Standard Model effective potential in an arbitrary curved spacetime is computed to one loop order in perturbation theory. The loop corrections ar…
Non-minimal gravitational reheating during kination
Konstantinos Dimopoulos, Tommi Markkanen
A new mechanism is presented which can reheat the Universe in non-oscillatory models of inflation, where the inflation period is followed by a period dominated by the kinetic densi…
