ShowingImportancePrizesTopicElectroweak vacuum stability
Whether the Standard Model Higgs potential is absolutely stable or only metastable up to the Planck scale, given the measured Higgs-boson and top-quark masses: stability/metastability boundary calculations, renormalization-group extrapolation of the quartic coupling, and how measurement and theoretical uncertainties affect the verdict. Not collider vacuum-bubble risk debates (see LHC safety) and n
The Higgs quartic coupling runs negative near 10^10 to 10^11 GeV for central Standard Model parameters.

Uncertainties in the top-quark mass leave absolute electroweak vacuum stability consistent with current measurements.

Absolute electroweak vacuum stability requires a top-quark pole mass below about 171 GeV

The predicted lifetime of the metastable electroweak vacuum vastly exceeds the current age of the universe.
