Electroweak scale

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 $v=(G_{F}{\sqrt {2}})^{{-1/2}}$ of the Higgs field (where $G_{F}$ is the Fermi coupling constant).
