Can 2HDM support fermion-stabilized bubbles of false vacuum?
I. P. Ivanov
TL;DR
This paper explores the potential of the two-Higgs-doublet model to support microscopic false vacuum bubbles stabilized by heavy fermions, which could prevent bubble collapse.
Contribution
It introduces a novel mechanism where heavy fermions trapped in false vacuum bubbles can stabilize them within the two-Higgs-doublet model.
Findings
Heavy fermions can stabilize false vacuum bubbles.
Fermion trapping affects vacuum stability.
Potential implications for early universe cosmology.
Abstract
The Higgs potential of the two-Higgs-doublet model can have several minima with different properties. We discuss a possibility that a heavy fermion, if trapped in a microscopic false vacuum bubble, might become light enough to prevent the bubble from the collapse.
