Electroweak scale
From Free net encyclopedia
In particle physics, the electroweak scale is the energy scale around 246 GeV, a typical energy of processes described by the electroweak theory. The particular number 246 GeV is taken to be the vacuum expectation value <math>v = (G_F \sqrt{2})^{-1/2}</math> of the Higgs field (where <math>G_F</math> is the Fermi coupling constant).
