"dphi_mu_met SR" of "Improved reconstruction of highly boosted $\tau$-lepton pairs in the $\tau\tau\rightarrow(\mu\nu_{\mu}\nu_{\tau})({hadrons}+\nu_{\tau})$ decay channels with the ATLAS detector"

The distribution of $\Delta\phi^\mathrm{signed}_{\mu-MET}$ with all other event selection criteria applied in the SR; the straight lines indicate the positions of the selection requirements. `$Z(\rightarrow\tau\tau)+\text{jets}$' represents the contributions from the signal process. `Diboson' indicates the contributions from $WW$, $WZ$, and $ZZ$ processes. `Top' represents the predicted contributions from the $t\bar{t}$, single-top, and $tW$ processes. `Other' includes the contributions from the $Z(\rightarrow\ell\ell)$+jets, $W$+jets, and Higgs boson processes. The uncertainties shown include both statistical and systematic errors.

本图展示了在信号区域（SR）中应用全部其他事件选择判据后，μ子与缺失横向动量间的符号化方位角差（$Deltaphi^mathrm{signed}_{mu-MET}$）的分布；其中直线标注了选择要求的对应位置。`$Z(
ightarrow au au)+ ext{jets}$` 代表信号过程的贡献。双玻色子（Diboson）表示$WW$、$WZ$及$ZZ$过程的贡献。顶夸克相关过程（Top）代表$tar{t}$、单顶夸克以及$tW$过程的预期贡献。其他背景（Other）包含$Z(
ightarrowellell)+ ext{jets}$、$W+ ext{jets}$以及希格斯玻色子过程的贡献。图中展示的不确定度同时涵盖统计误差与系统误差。
