trailThe Standard Model electroweak vacuum is metastable rather than absolutely stable.
A high-energy particle collision could trigger the universe's vacuum to decay into a more stable state.
Running of the Higgs quartic coupling· for
The Higgs quartic coupling runs negative near 10^10 to 10^11 GeV for central Standard Model parameters.
Direct measurements determine the top-quark mass near 172.5 GeV with uncertainty below 0.5 GeV
Absolute electroweak vacuum stability requires a top-quark pole mass below about 171 GeV
◌
◌
Parameter uncertainties leave stability open· against
Uncertainties in the top-quark mass leave absolute electroweak vacuum stability consistent with current measurements.
Top-quark pole-mass determinations from cross sections have uncertainties of about 0.7 GeV
The Monte Carlo top-quark mass equals the pole mass to within a few hundred MeV
