Higgs self coupling

Web30 de jul. de 2024 · This self-coupling can only be measured directly by studying the production of pairs of Higgs bosons (HH). However, Higgs-boson-pair production in the Standard Model is very rare – a factor of thousand less likely than for the production of a single Higgs boson. WebThe usual presentation of the super-Higgs mechanism introduces Goldstino and Gravitino self-couplings (or mass terms) by hand and shows that the resulting action is consistent under local supersymmetry [ 2 ]. One then applies a shift of the Gravitino to obtain a massive Gravitino action coupled to matter supercurrents.
