Higgs self coupling
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. WebBased on our experience, we plan to study di-Higgs boson production, which is essential to probe the important Higgs boson self-coupling, in the !! → $$ %%& decay mode.
