TL;DR
This paper reviews the stability of the electroweak vacuum in the Standard Model after the Higgs discovery, discussing the implications of the Higgs mass and potential solutions to vacuum instability.
Contribution
It provides a concise review of electroweak vacuum stability issues in the Standard Model and explores possible methods to ensure stability without new physics.
Findings
The Higgs mass suggests the vacuum may be metastable.
Vacuum stability depends on precise measurements of Standard Model parameters.
Possible solutions include new physics or modifications to the Standard Model.
Abstract
The long-awaited Higgs particle H around 125 GeV has been observed at the LHC. Interpreting it as the standard model Higgs boson and if there is no new physics between electroweak and Planck scale, we then don't have a stable vacuum. Here, we give a brief review of the electroweak vacuum stability and some related theoretical issues in the standard model. Possible ways to save the stability are also discussed.
