Higgs boson pairs produced non-resonantly or in the decay of a narrow-width scalar resonance in the mass range 251 to 1600 GeV are targeted. Events in which at least one tau-lepton decays hadronically are considered, and multivariate discriminants are used to reject the backgrounds. No significant excess of events above the expected background is observed in the non-resonant search. The largest excess in the resonant search is observed at a resonance mass of 1 TeV, with a local (global) significance of 3.1 sigma (2.0 sigma). Observed (expected) upper limits are set at the 95% confidence-level on the non-resonant Higgs boson pair production cross-section of 4.7 (3.9+1.5\u22121.1) times the Standard Model prediction, assuming Standard Model kinematics, and on the resonant Higgs boson pair production cross-section between 21 and 900 fb (12 and 840 fb), depending on the heavy resonance mass.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.130794.v1/t1","@type":"Dataset","description":"Breakdown of the relative contributions to the uncertainty in the extracted signal cross-sections, as determined in the likelihood fit (described...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.130794.v1/t2","@type":"Dataset","description":"Post-fit expected number of signal and background events and observed number of data events in the last two bins of...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.130794.v1/t3","@type":"Dataset","description":"Observed and expected upper limits at 95% CL on the cross-section of non-resonant HH production according to SM-like kinematics, and...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.130794.v1/t4","@type":"Dataset","description":"Cumulative efficiency for simulated signal events to pass each stage of the event selection in the hadhad category.
