description: The 95% CL observed limits, expected limits and ± 1 σ and 2 σ bands for the Φ mass 125 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: Efficiency for an event to enter Region A of the high-E<sub>T</sub> selection, as a function of the two LLP kinematics, decay type and decay position. LLP p<sub>T</sub> is binned in the ranges of [0, 50 , 100, 200 , 400, 1600] GeV (5 bins), the LLP decay position is binned in decay position in L<sub>xy</sub> in [0, 1.5, 2, 2.5, 3, 3.5, 3.9, ∞] m for LLPs with |η| &lt; 1.5 and L<sub>z</sub> in [0, 3.6, 4.2, 4.8, 5.5, 6, ∞ ] m for LLPs with |η|geq1.5, 13 bins in all. Finally, four decay types are considered: LLPs decaying to pairs of c, b, t, or τ in bins 0, 1, 2, 3 respectively. The efficiency is presented as a function of "Bin Index", which is calculated as follows: Bin Index = (decay position bin index ) × (number of decay position bins × number of decay type bins) + p<sub>T</sub> bin index * (number of decay type bin) + decay type bin index. The efficiency for a given pair-produced LLP sample can be obtained by summing the efficiency values for each event as extracted from this map, and dividing it by the total number of events in the sample. The efficiency map is symmetric between the LLPs, so the choice of LLP1 and LLP2 is arbitrary. For the high-E<sub>T</sub> selections, for overall efficiencies above 0.5%, the results are typically accurate to around 25%, but below this the efficiency can be overestimated and therefore should not be used for re-interpration.
