A search for resonant and non-resonant Higgs boson pair production in the bb¯τ+τ− decay channel in pp collisions at √s = 13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

A search for resonant and non-resonant pair production of Higgs bosons in the bb¯τ+τ− final state is presented. The search uses 36.1 fb−1 of pp collision data with s√=13 TeV recorded by the ATLAS experiment at the LHC in 2015 and 2016. The semileptonic and fully hadronic decays of the τ-lepton pair are considered. No significant excess above the expected background is observed in the data. The cross-section times branching ratio for non-resonant Higgs boson pair production is constrained to be less than 30.9 fb, 12.7 times the Standard Model expectation, at 95% confidence level. The data are also analyzed to probe resonant Higgs boson pair production, constraining a model with an extended Higgs sector based on two doublets and a Randall-Sundrum bulk graviton model.
