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. WebTheorem and the accompanying massless Goldstone particles. Then, by adding gauge vector bosons we explain how the massless Goldstone and vector particles can be avoided, which is called the Higgs mechanism. In the last part of the paper we try to flnd a similar working Higgs mechanism model for General Relativity, which makes the graviton …
