Early Universe Higgs dynamics in the presence of the Higgs-inflaton and non-minimal Higgs-gravity couplings

Understand

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 during and after inflation.
• Higgs-inflaton and non-minimal Higgs-gravity interactions can make a crucial impact on these considerations potentially solving the problems.
• In this work, we allow for these couplings to be present simultaneously and study their interplay.
