Key points
- Standard Model parameters extracted with full 2-loop NNLO precision.
- Extrapolation of parameters to high energies uses full 3-loop NNLO RGE precision.
- Measured Higgs mass corresponds to near-critical values of Higgs quartic, top Yukawa, and gauge couplings.
- The Standard Model vacuum may be metastable.

Abstract
A bstract We extract from data the parameters of the Higgs potential, the top Yukawa coupling and the electroweak gauge couplings with full 2-loop NNLO precision, and we extrapolate the SM parameters up to large energies with full 3-loop NNLO RGE precision. Then we study the phase diagram of the Standard Model in terms of high-energy parameters, finding that the measured Higgs mass roughly corresponds to the minimum values of the Higgs quartic and top Yukawa and the maximum value of the gauge couplings allowed by vacuum metastability. We discuss various theoretical interpretations of the near-criticality of the Higgs mass.
