Higgs-Inflaton Mixing and Vacuum Stability
Yohei Ema, Mindaugas Karciauskas, Oleg Lebedev +2
The quartic and trilinear Higgs field couplings to an additional real scalar are renormalizable, gauge and Lorentz invariant. Thus, on general grounds, one expects such couplings b…
Early Universe Higgs dynamics in the presence of the Higgs-inflaton and non-minimal Higgs-gravity couplings
Yohei Ema, Mindaugas Karciauskas, Oleg Lebedev +1
Apparent metastability of the electroweak vacuum poses a number of cosmological questions. These concern evolution of the Higgs field to the current vacuum, and its stability durin…
Postinflationary vacuum instability and Higgs-inflaton couplings
Kari Enqvist, Mindaugas Karciauskas, Oleg Lebedev +2
The Higgs-inflaton coupling plays an important role in the Higgs field dynamics in the early Universe. Even a tiny coupling generated at loop level can have a dramatic effect on th…
Higgs-inflaton coupling from reheating and the metastable Universe
Christian Gross, Oleg Lebedev, Marco Zatta
Current Higgs boson and top quark data favor metastability of our vacuum which raises questions as to why the Universe has chosen an energetically disfavored state and remained the…
