Webv is the vacuum expectation value of the Higgs field, v = (√ 2GF)−1/2 ≈ 246 GeV, fixed by the Fermi coupling GF,which is determined precisely from muon decay measurements [24]. Since λ is presently unknown, the value of the SM Higgs boson mass mH cannot be predicted. However, besides the upper bound on the Higgs boson mass from ...
