Investigating the nearcriticality of the Higgs boson
Abstract
We extract from data the parameters of the Higgs potential, the top Yukawa coupling and the electroweak gauge couplings with full 2loop NNLO precision, and we extrapolate the SM parameters up to large energies with full 3loop NNLO RGE precision. Then we study the phase diagram of the Standard Model in terms of highenergy 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 nearcriticality of the Higgs mass.
