Název v původním jazyce

Search for doubly charged Higgs boson production in multi-lepton final states using 139 fb-1 of proton–proton collisions at √s= 13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

A search for pair production of doubly charged Higgs bosons (H±±H±±), each decaying into a pair of prompt, isolated, and highly energetic leptons with the same electric charge, is presented. The search uses a proton–proton collision data sample at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 139 fb−1−1 recorded by the ATLAS detector during Run 2 of the Large Hadron Collider (LHC). This analysis focuses on same-charge leptonic decays, H±± ⁣→ℓ±ℓ′±H±±→ℓ±ℓ′± where ℓ,ℓ′ ⁣= ⁣e,μ,τℓ,ℓ′=e,μ,τ, in two-, three-, and four-lepton channels, but only considers final states which include electrons or muons. No evidence of a signal is observed. Corresponding upper limits on the production cross-section of a doubly charged Higgs boson are derived, as a function of its mass m(H±±)m(H±±), at 95% confidence level.
