Can the universe become stable with a new electroweak vacuum

Click For Summary
SUMMARY

The discussion centers on the electroweak vacuum metastability and its implications for the stability of the universe. Current data suggests that the universe is positioned at the edge of stability, leaning towards the meta-stable region, which is supported by 3-loop renormalization group calculations. The relationship between the electroweak vacuum and the masses of the top quark and Higgs boson is critical, as changes in the vacuum affect these masses. Further research is necessary to clarify how the boundaries of stability and meta-stability shift, particularly in light of new high-energy physics that could influence the Higgs potential.

PREREQUISITES
  • Understanding of electroweak vacuum metastability
  • Familiarity with Higgs boson and top quark mass determination
  • Knowledge of 3-loop renormalization group techniques
  • Basic concepts of quantum field theory
NEXT STEPS
  • Research the implications of new high-energy physics on electroweak vacuum stability

  • Explore advanced topics in quantum field theory related to vacuum states
  • Examine recent publications on electroweak vacuum metastability, such as those on arXiv
USEFUL FOR

Physicists, researchers in high-energy physics, and students studying quantum field theory who are interested in the stability of the universe and electroweak interactions.

The top and Higgs mass determination arose the old discussion about electroweak vacuum metastablity. There is an interesting fact that with available data the universe places in the edge of stable and meta-stable zone tends to be inside the meta-stable region. This conclusion confirms up to 3-loop renormalization group and even shows convergence. I know that changing the electroweak vacuum propertionally changes the top and higgs masses. But what I can't realize is that how the stability and meta-stability boundaries movem in this situation. So to speak, can the universe become stable by new high energy physics emergence as just <h>=246 Gev replacement?
