Webdiscovered Higgs boson with the inflaton condensate. Unfortunately, the Higgs self-interaction significantly exceeds the value ˘10 13 leading to a sufficiently long inflationary period without generating an excessively large spectrum of primordial density perturbations [6]. The situation 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 …

WebInstead, to obtain additional insight, we take one step back from this and will address the question of “how” the Gravitino and Goldstino obtain these self-couplings. This approach is strongly analogous to that of the Higgs mechanism presented by Englert and Brout [] (see also an excellent review of these topics []).In this approach we start from a classical … WebThe Higgs self-interactions play a crucial role in exploring the underlying mechanisms of electroweak symmetry breaking and the nature of the phase transition involved.
