Web13 de nov. de 2010 · Higgs gives his version of the history here, and refers to the “Anderson mechanism”, writing: During October 1964, Higgs had discussions with Gerald Guralnik, Carl Hagen and Tom Kibble, who had discovered how the mass of non-interacting vector bosons can be generated by the Anderson mechanism. Guralnik, Hagen and Kibble had … WebThe Higgs mechanism breaks electroweak symmetry in the Standard Model, giving mass to particles through its couplings. Current data from electroweak precision measurements points to a light Higgs (MHiggs ≪ 199 GeV @ 95% CL [1] ). However, the Higgs has never been definitively observed ( MHiggs > 114 GeV at 95% CL [2] ).

Web7 de dez. de 2011 · A photon in a superconductor gets a mass, and this is the Higgs mechanism. For a relativistic boson described by a scalar field, you give the field a constant nonzero value to make a condensate. When the field has charge, this makes a superconducting condensate which gives the gauge boson a mass. WebThe Higgs Mechanism The assumption is made that the universe is filled with a spin-zero field, called a Higgs field, which is a doublet in SU(2) and with a nonzero U(1) hypercharge, but a singlet in color space . The gauge bosons and fermions can interact with this field, and in this interaction they acquire mass.
