Search for triple Higgs boson production in the 6b final state using pp collisions at √s=13 TeV with the ATLAS detector
A search for the production of three Higgs bosons (𝐻𝐻𝐻) in the 𝑏¯𝑏𝑏¯𝑏𝑏¯𝑏 final state is presented. The search uses 126 fb−1 of proton-proton collision data at √𝑠 =13 TeV collected with the ATLAS detector at the Large Hadron Collider. The analysis targets both nonresonant and resonant producti...

| Zusammenfassung: | A search for the production of three Higgs bosons (𝐻𝐻𝐻) in the 𝑏¯𝑏𝑏¯𝑏𝑏¯𝑏 final state is presented. The search uses 126 fb−1 of proton-proton collision data at √𝑠 =13 TeV collected with the ATLAS detector at the Large Hadron Collider. The analysis targets both nonresonant 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 and 1 TeV, respectively. In addition to scenarios where 𝑆 is off-shell, the nonresonant interpretation includes a search for Standard Model 𝐻𝐻𝐻 production, with limits on the trilinear and quartic Higgs self-coupling set. No evidence for 𝐻𝐻𝐻 production is observed. An upper limit of 59 fb is set, at the 95% confidence level, on the cross section for Standard Model 𝐻𝐻𝐻 production. |
