"Distribution 1" of "Search for new phenomena in final states with photons, jets and missing transverse momentum in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector"

Observed (points with error bars) and expected background (solid histograms) distributions for $E_{T}^{miss}$ in the signal region (a) SRL, (b) SRM and (c) SRH after the background-only fit applied to the CRs. The predicted signal distributions for the two models with a gluino mass of 2000 GeV and neutralino mass of 250 GeV (SRL), 1050 GeV (SRM) or 1950 GeV (SRH) are also shown for comparison. The uncertainties in the SM background are only statistical.

本数据集呈现了将仅背景拟合应用于控制区（Control Region，CR）后，信号区（Signal Region，SR）(a) SRL、(b) SRM 与 (c) SRH 内的缺失横向动量（Missing Transverse Energy，$E_{T}^{miss}$）观测分布（带误差棒的数据点）与预期本底分布（实心直方图）。同时还展示了两类模型的预期信号分布以供对比：这两类模型的胶微子（gluino）质量均为2000 GeV，其中对应SRL信号区的中性微子（neutralino）质量为250 GeV，对应SRM信号区的为1050 GeV，对应SRH信号区的为1950 GeV。标准模型（Standard Model，SM）本底的不确定性仅包含统计不确定性。
