| Sumario: | We thank CERN for the very successful operation of the LHC and its injectors, as well as the support staff at CERN and at our institutions worldwide without whom ATLAS could not be operated efficiently. The crucial computing support from all WLCG partners is acknowledged grate- fully, in particular from CERN, the ATLAS Tier-1 facilities at TRIUMF/SFU (Canada), NDGF (Denmark, Norway, Sweden), CC-IN2P3 (France), KIT/GridKA (Germany), INFN-CNAF (Italy), NL-T1 (Netherlands), PIC (Spain), RAL (UK) and BNL (USA), the Tier-2 facilities worldwide and large non-WLCG resource providers. Major contrib- utors of computing resources are listed in Ref. [106].

Left to right: the number of events expected by the SM, the number of events observed, 95% CL upper limits on the visible cross section (hϵσi95 obs ) and on the number of signal events (S95 obs ). The fifth column (S95 exp ) shows the 95% CL upper limit on the number of signal events, given the expected number (and 1σ excursions on the expectation) of background events. The last column indicates the CL b value, i.e. the confidence level observed for the background-only hypothesis. The discovery p-value [pðs ¼ 0Þ] is 0.50 with significance (Z) of 0 for all presented mass ranges. The discovery limits were derived using 10,000 pseudo-experiments.
