Implication

This analysis demonstrates vacuum stability conditions in theoretical models, highlighting Higgs mass constraints and implications for particle physics.

Key Points

The study aims to determine the stability of the Standard Model vacuum based on the Higgs mass and top quark mass.
Conducted a one-loop calculation of tunnelling probability at zero temperature.
Utilized two-loop renormalization-group equations for improved accuracy.
Analyzed lower bounds on the Higgs mass imposed by vacuum stability requirements.
Found instability in the Higgs potential for m_H=115 GeV with top quark mass m_t > (166 ± 2) GeV.
Confirmed the electroweak vacuum is sufficiently long-lived for m_t min(175 ± 2) GeV.
