title: "Post-fit data/background in ee channel" of "Search for dark photons from Higgs boson decays via $ZH$ production with a photon plus missing transverse momentum signature from $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector"

description: Distribution of the BDT classifier response in data and for the expected SM background after the background-only fit, in the ee channel. The expectations for signal are also shown for the massless dark photon and for dark photon mass values of 20 GeV and 40 GeV, assuming BR(H$\to\gamma\gamma_d$) = 5%. Uncertainties shown are statistical for data, while for backgrounds include statistical and systematic sources.
description: This paper describes a search for dark photon ($\gamma_d$) in Higgs boson decay (H$\to\gamma\gamma_d$) produced in proton-proton collisions through the ZH production mode at the Large Hadron Collider (LHC) at $\sqrt{s}$=13 TeV. The transverse mass of the photon and the missing transverse momentum from the non-interacting gamma_d present a distinctive signature as it peaks near the Higgs boson mass. The results presented use the total Run-2 integrated luminosity of 139fb$^{-1}$ recorded by the ATLAS detector at the LHC. The dominant reducible background processes have been estimated using data-driven techniques. A Boosted Decision Tree technique was adobted to enhance the sensitivity of the search.

title: "Figure 2a" of "Search for supersymmetry in final states with a single electron or muon using angular correlations and heavy-object identification in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: Signal and background distributions of the $\Delta \phi$ variable, as predicted by simulation, for the multi-b analysis, requiring $n_{\textrm{jet}}\geq6$, $L_T&gt;250~\mathrm{GeV}$, $H_T&gt;500~\mathrm{GeV}$. The predicted signal distributions are also shown for two representative combinations of (gluino, neutralino) masses with large (2.2, 0.1) $\mathrm{TeV}$ and small (1.8, 1.3) $\mathrm{TeV}$ mass differences.
description: A search for supersymmetry is presented in events with a single charged lepton, electron or muon, and multiple hadronic jets. The data correspond to an integrated luminosity of 138 $\textrm{fb}^{-1}$ of proton-proton collisions at a center-of-mass energy of 13 $\textrm{TeV}$, recorded by the CMS experiment at the CERN LHC. The search targets gluino pair production, where the gluinos decay into final states with the lightest supersymmetric particle (LSP) and either a top quark-antiquark ($\textrm{t}\bar{\textrm{t}}$) pair, or a light-flavor quark-antiquark ($\textrm{q}\bar{\textrm{q}}$) pair and a virtual or on-shell $\textrm{W}$ boson. The main backgrounds, $\textrm{t}\bar{\textrm{t}}$ pair and $\textrm{W}$+jets production, are suppressed by requirements on the azimuthal angle between the momenta of the lepton and of its reconstructed parent $\textrm{W}$ boson candidate, and by top quark and $\textrm{W}$ boson identification based on a machine-learning technique. The number of observed events is consistent with the expectations from standard model processes. Limits are evaluated on supersymmetric particle masses in the context of two simplified models of gluino pair production. Exclusions for gluino masses reach up to 2120 (2050) $\textrm{GeV}$ at 95% confidence level for a model with gluino decay to a $\textrm{t}\bar{\textrm{t}}$ pair (a $\textrm{q}\bar{\textrm{q}}$ pair and a $\textrm{W}$ boson) and the LSP. For the same models, limits on the mass of the LSP reach up to 1250 (1070) $\textrm{GeV}$.
