Electroweak scale

In particle physics, the electroweak scale, also known as the Fermi 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 ${\displaystyle v=(G_{F}{\sqrt {2}})^{-1/2}}$ of the Higgs field (where ${\displaystyle G_{F}}$ is the Fermi coupling constant). In some cases the term electroweak scale is used more loosely to refer to energies in a broad range around 100-1000 GeV.
