Probing the quartic Higgs boson self-interaction

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. Webcontains the Higgs three-point and four-point self interaction terms, contains the Higgs interactions with gauge vector bosons, contains the gauge three-point self interactions, contains the gauge four-point self interactions, contains the Yukawa interactions between the fermions and the Higgs field, See also [ edit] Electroweak star sonesta maho resort in sint maarten
