Web1 de nov. de 2024 · The principal Feynman diagrams of the pair production of Higgs bosons via ggF. Left: Higgs self-coupling diagram. Right: top box diagram. If one stays with the SM parameters, the cross-section for the HH production and the kinematics of the Higgs bosons being produced is fully defined. Webits measurement via triple Higgs production seems beyond the reach of the LHC [26,27] due to the smallness of the corresponding cross section (around 0:1 fb) [20]. In order to constrain the trilinear Higgs self coupling, a complementary strategy based on the precise measurements of single Higgs production and decay processes was recently proposed.
