In some cases the term electroweak scale is used to refer to the temperature of electroweak symmetry breaking, 159.5±1.5 GeV[1] .
In other cases, the term is used more loosely to refer to energies in a broad range around 102 - 103 GeV.
This is within reach of the Large Hadron Collider (LHC), which is designed for about 104 GeV in proton–proton collisions.
In the unextended Standard Model, the transition from the electroweak epoch was not a first or a second order phase transition but a continuous crossover, preventing any baryogenesis.
[2] However many extensions to the standard model including supersymmetry and the inert double model have a first order electroweak phase transition (but still lack additional CP violation).
