Twice the Higgs, twice the challenge ATLAS Experiment at CERN

The Higgs mechanism occurs whenever a charged field has a vacuum expectation value. In the non-relativistic context this is a superconductor, more formally known as the Landau model of a charged Bose–Einstein condensate. In the relativistic condensate, the condensate is a scalar field that is relativistically invariant. WebThe Higgs field can be thought of as a giant field of energy, with the Higgs Bosons being excitations in that field. This field interacts with particles to give them mass, and this is …
