Constraints on inert dark matter from metastability of the electroweak vacuum
Najimuddin Khan, Subhendu Rakshit
TL;DR
This paper investigates how the inert scalar doublet dark matter model affects the stability of the electroweak vacuum, identifying parameter regions that ensure absolute stability or metastability up to the Planck scale.
Contribution
It provides a comprehensive analysis of the parameter space in the inert doublet model that maintains vacuum stability or metastability up to the Planck scale.
Findings
Certain parameter regions lead to absolute vacuum stability.
Other regions result in metastability of the electroweak vacuum.
The model remains valid up to the Planck scale under specific conditions.
Abstract
The inert scalar doublet model of dark matter can be valid up to the Planck scale. We briefly review the bounds on the model in such a scenario and identify parameter spaces that lead to absolute stability and metastability of the electroweak vacuum.
