title: "Figure 6f of Aux. Mat." of "Search for neutral long-lived particles in $pp$ collisions at $\sqrt{s}=13$ TeV that decay into displaced hadronic jets in the ATLAS calorimeter"

description: The 95% CL observed limits, expected limits and ± 1 σ and 2 σ bands for the Φ masses of of 1000 GeV, compared to the results from the 2016-data analysis and subsequent combinations, where available.
description: A search for decays of neutral long-lived particles (LLPs) is presented using 139/fb of proton-proton collisions data collected by the ATLAS detector at the LHC in 2015--2018 at a center-of-mass energy of 13 TeV. Dedicated techniques are developed in this search for the reconstruction of displaced jets produced by LLPs decaying hadronically in the ATLAS hadronic calorimeter. Two search regions are defined for different LLP kinematic regimes. The observed numbers of events are consistent with the expected background and limits for several benchmark signals are determined. For a scalar boson with a mass of 125 GeV, branching ratios above 10% are excluded at 95% confidence level for LLP proper decay lengths in the range between 2 cm and 10 m depending on the model. Upper limits are also set on the cross-section times branching ratio for heavy scalars with a mass of 60 GeV and for masses between 200 GeV and 1 TeV.

description: CalRatio triggers which were available during the LHC Run 2 data-taking, and corresponding integrated luminosity collected in each period. The high-E<sub>T</sub> CalRatio trigger with E<sub>T</sub> &gt; 60 GeV was disabled in 2017 for instantaneous luminosities higher than 1.4 × 10<sup>34</sup> cm<sup>-2</sup> s<sup>-1</sup>. Two versions of the low-E<sub>T</sub> CalRatio trigger were used, with slight differences in their algorithms. The details are reported in Section 4.

description: Application of the modified ABCD method to the final high-E<sub>T</sub> selections. The a priori estimate refers to the "pre-unblinding" case, where the data in region A are ignored by removing the Poisson constraint in that region and the signal strength is fixed to zero. This matches the simple N<sup>bkg</sup><sub>A</sub>=(N<sup>bkg</sup><sub>B</sub>· N<sup>bkg</sup><sub>C</sub>)/N<sup>bkg</sup><sub>D</sub> relation. The a posteriori estimate refers to the "post-unblinding" case, including the observed data in region A in the background-only global fit, obtained by fixing the signal strength to 0 (background-only fit) or allowing it to float (signal-plus-background fit). The table also shows one set of representative signal yields in each selection for the signal-plus-background fit. Only statistical uncertainties are included in the quoted error of the background, while the uncertainties in the signal include those from both statistical and experimental sources.
