Palavras-chave: | Beyond Standard Model; Hadron-Hadron scattering (experiments); Higgs physics | Data: | 2018 | Editora: | Springer Nature | Título da revista, periódico, livro ou evento: | Journal of High Energy Physics | Volume: | 2018 | Número: | 11 | Resumo: | A search for charged Higgs bosons heavier than the top quark and decaying via H ! tb is presented. The data analysed corresponds to 36.1 fb1 of pp collisions at p s = 13TeV and was recorded with the ATLAS detector at the LHC in 2015 and 2016. The production of a charged Higgs boson in association with a top quark and a bottom quark, pp ! tbH , is explored in the mass range from mH = 200 to 2000 GeV using multi-jet nal states with one or two electrons or muons. Events are categorised according to the multiplicity of jets and how likely these are to have originated from hadronisation of a bottom quark. Multivariate techniques are used to discriminate between signal and background events. No signi cant excess above the background-only hypothesis is observed and exclusion limits are derived for the production cross-section times branching ratio of a charged Higgs boson as a function of its mass, which range from 2.9 pb at mH = 200 GeV to 0.070 pb at mH = 2000 GeV. The results are interpreted in two benchmark scenarios of the Minimal Supersymmetric Standard Model. | URI: | https://hdl.handle.net/10316/107722 | DOI: | 10.1007/JHEP11(2018)085 | Direitos: | openAccess |
