... • Introducing a pair of complex scalar fields with a locus of degenerate minima generates 3 Goldstone bosons that give masses to the weak bosons and a 4th scalar: the Higgs boson • More complex schemes are possible with several Higgs bosons, but the mechanism remains the same • However no Higgs boso ...

... With light [ E≈1eV] we can "see"the structure of matter down to 10-6m. To see the structure of matter at a scale of 10-18 m and below we need probes with an energy of one TeV [= 1012 eV] or above. ...
