The paper investigates the near-criticality of the Higgs boson mass in the Standard Model (SM). It extracts parameters of the Higgs potential, top Yukawa coupling, and electroweak gauge couplings with high precision, and extrapolates SM parameters to high energies. The results show that the measured Higgs mass is near the critical value where the Higgs vacuum is metastable. This near-criticality suggests that the SM vacuum is close to a phase transition, which has significant implications for high-energy physics. The study provides precise calculations of the Higgs quartic coupling, top Yukawa coupling, and electroweak gauge couplings at NNLO precision. These results are used to analyze the SM phase diagram and assess the stability of the vacuum. The paper also discusses various theoretical interpretations of the near-criticality, including the possibility of criticality as an attractor and the double criticality of Higgs and top couplings. The results are relevant for testing new physics scenarios, such as gauge coupling unification and high-scale supersymmetric models. The study highlights the importance of accurate calculations for understanding the behavior of the SM at high energies and the potential for new physics beyond the Standard Model.The paper investigates the near-criticality of the Higgs boson mass in the Standard Model (SM).
