Higgs condensate
WebThe Higgs mechanism 'starts' with four massless bosons ( B 0, W 0, W 1, W 2 ), which after some interacting with the Higgs field, will produce three massive bosons ( Z, W +, W −) and one massless boson (which is the photon, γ ). Spontaneous symmetry breaking offered a framework to introduce bosons into relativistic quantum field theories. However, according to Goldstone's theorem, these bosons should be massless. The only observed particles which could be approximately interpreted as Goldstone bosons were the pions, which Yoichiro Nambu related to chiral symmetry breaking.
