The proposed Higgs mechanism arose as a result of theories proposed to explain observations in superconductivity. A superconductor won't allow penetration by exterior magnetic fields (the Meissner result). Yang and Mills work on non-abelian gauge concept experienced just one huge issue: in perturbation concept it's got massless particles which https://www.facebook.com/johnbesttoolsmarketing/posts/pfbid02fTexTrnVvg3gpL2bURspqs11JiC8RiPzGFkd7Kfd6XYiwLKpgrzjha3HZq8bM9m1l
