Título: | Search for a heavy Higgs boson decaying into a Z boson and another heavy Higgs boson in the bb and WW final states in pp collisions at √ s = 13 TeV with the ATLAS detector | Autor: | Fiolhais, M. C. N. Gonçalo, R. Veloso, F. Wolters, H. ATLAS Collaboration |
Data: | Mai-2021 | Editora: | Springer Nature | Título da revista, periódico, livro ou evento: | European Physical Journal C | Volume: | 81 | Número: | 5 | Resumo: | A search for a heavy neutral Higgs boson, A, decaying into a Z boson and another heavy Higgs boson, H, is performed using a data sample corresponding to an integrated luminosity of 139 fb−1 from proton–proton collisions at √ s = 13 TeV recorded by the ATLAS detector at the LHC. The search considers the Z boson decaying into electrons or muons and the H boson into a pair of b-quarks or W bosons. The mass range considered is 230–800 GeV for the A boson and 130–700 GeV for the H boson. The data are in good agreement with the background predicted by the Standard Model, and therefore 95% confidence-level upper limits for σ × B(A → ZH) × B(H → bb or H → WW) are set. The upper limits are in the range 0.0062–0.380 pb for the H → bb channel and in the range 0.023–8.9 pb for the H → WW channel. An interpretation of the results in the context of two-Higgs-doublet models is also given. | URI: | https://hdl.handle.net/10316/103910 | DOI: | 10.1140/epjc/s10052-021-09117-5 | Direitos: | openAccess |
