Description
Ref. ATLAS-HIGP-2024-32
A search for production of three Higgs bosons (HHH) in the 6b final state is presented. The search uses 126 fb−1 of pp collision data at √s = 13 TeV collected with the ATLAS detector at the Large Hadron Collider. The analysis targets both non-resonant and resonant production of HHH. The resonant interpretations primarily consider a cascade decay topology of X→SH→HHH with masses of the new scalars X and S up to 1.5 TeV and 1 TeV, respectively. In addition to scenarios where S is off-shell, the non-resonant interpretation includes a search for SM-like HHH production, with limits on the tri-linear and quartic Higgs self-coupling set. No evidence for HHH production is observed.
