... with a (set of) scalar field(s) φ) there is an electroweak phase transition at a transition temperature of T ∼ 300 GeV ∼ 1015 K when the universe was ∼ 10−11 s old. Above this phase transition the Higgs field expectation value vanishes < φ >= 0. This transition translates into zero rest masses of al ...
