WebThe Higgs field has a vacuum expectation value of 246 GeV. [1] This nonzero value underlies the Higgs mechanism of the Standard Model. This value is given by , where MW is the mass of the W Boson, the reduced Fermi constant, and g the weak isospin coupling, in natural units. It is also near the limit of the most massive nuclei, at v = 264.3 Da. WebarXiv.org e-Print archive
