Web4 de jul. de 2024 · The self-interaction is also expected to impact processes in which only a single Higgs boson is produced. This is due to the presence of higher order corrections to the single Higgs cross-section, accounting for a small contribution to the total production … 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. shapes chantilly
