title: "Fit for Stealth SYY $2\ell$ Channel ($m_{\tilde{t}} = 400$ GeV)" of "Search for top squarks in final states with many light-flavor jets and 0, 1, or 2 charged leptons in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: The $N_{jets}$ distributions from the background-only fits to data in the $2\ell$. The signal distribution overlaid corresponds to the Stealth SYY model with $m_{\tilde{t}} = 400$ GeV with the signal strength parameter $r$ set to one. The four pannels in each row show the $N_{jets}$ distributions for the A, B, C, and D regions (left to right).
description: Several new physics models including versions of supersymmetry (SUSY) characterized by$R$-parity violation (RPV) or with additional hidden sectors predict the productionof events with top quarks, low missing transverse momentum, and many additionalquarks or gluons.The results of a search for top squarks decaying to two top quarks and six additionallight-flavor quarks or gluons are reported.The search employs a novel machine learning method for backgroundestimation from control samples in data using decorrelated discriminators.The search is performed using events with 0, 1, or 2 leptons (electrons, muons) in conjunctionwith at least six jets. No requirement is placed on the magnitude of the missing transverse momentum.The result is based on a sample of proton-proton collisions at $\sqrt{s} = 13$ TeV.corresponding to 138 $\mathrm{fb}^{-1}$ of integrated luminosity collected with the CMS detectorat the LHC in 2016--2018.The data are used to determine upper limits on the top squark pair productioncross section in the frameworks of RPV and stealth SUSY.Models with top squark masses less than 700 (920) GGeV are excluded at 95% confidencelevel for RPV (stealth) SUSY scenarios.

title: "Meas. 1: Fiducial cross section" of "Measurements of $W^+W^-$ production cross-sections in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector"

description: Measured fiducial cross-section compared with theoretical predictions from MiNNLO+Pythia8, Geneva+Pythia8, Sherpa2.2.12, and MATRIX2.1. The predictions are based on the NNPDF3.0 (red squares) and NNPDF3.1 luxQED (blue dots) PDF sets. The nNNLO predictions include photon-induced contributions (always using NNPDF3.1 luxQED) and NLO QCD corrections to the gluon-gluon initial state. The $q\bar{q}\rightarrow WW$ predictions from MiNNLO, Geneva, and Sherpa2.2.12 are combined with a Sherpa2.2.2 prediction of gluon-induced production, scaled by an inclusive NLO K-factor of 1.7. Inner (outer) error bars on the theory predictions correspond to PDF (the combination of scale and PDF) uncertainties. The MATRIX nNNLO QCD $\otimes$ NLO EW prediction using NNPDF3.1 luxQED, the best available prediction of the integrated fiducial cross-section, is in good agreement with the measurement.
description: Measurements of $W^+W^-\rightarrow e^\pm \nu \mu^\mp \nu$ production cross-sections are presented, providing a test of the predictions of perturbative quantum chromodynamics and the electroweak theory. The measurements are based on data from $pp$ collisions at $\sqrt{s}=13$ TeV recorded by the ATLAS detector at the Large Hadron Collider in 2015--2018, corresponding to an integrated luminosity of 140 fb$^{-1}$. The number of events due to top-quark pair production, the largest background, is reduced by rejecting events containing jets with $b$-hadron decays. An improved methodology for estimating the remaining top-quark background enables a precise measurement of $W^+W^-$ cross-sections with no additional requirements on jets. The fiducial $W^+W^-$ cross-section is determined in a maximum-likelihood fit with an uncertainty of 3.1%. The measurement is extrapolated to the full phase space, resulting in a total $W^+W^-$ cross-section of $127\pm4$ pb. Differential cross-sections are measured as a function of twelve observables that comprehensively describe the kinematics of $W^+W^-$ events. The measurements are compared with state-of-the-art theory calculations and excellent agreement with predictions is observed. A charge asymmetry in the lepton rapidity is observed as a function of the dilepton invariant mass, in agreement with the Standard Model expectation. A CP-odd observable is measured to be consistent with no CP violation. Limits on Standard Model effective field theory Wilson coefficients in the Warsaw basis are obtained from the differential cross-sections.

title: "Meas. 2: $p_{\mathrm{T}}^{\mathrm{lead.\,lep.}}$" of "Measurements of $W^+W^-$ production cross-sections in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector"

description: Fiducial differential cross-sections as a function of $p_{\mathrm{T}}^{\mathrm{lead.\,lep.}}$. The measured cross-section values are shown as points with error bars giving the statistical uncertainty and solid bands indicating the size of the total uncertainty. The right-hand-side axis indicates the integrated cross-section of the rightmost bin. The results are compared to fixed-order nNNLO QCD + NLO EW predictions of Matrix 2.1, with the NNLO + PS predictions from Powheg MiNNLO + Pythia8 and Geneva + Pythia8, as well as Sherpa2.2.12 NLO + PS predictions. The last three predictions are combined with Sherpa 2.2.2 for the $gg$ initial state and Sherpa 2.2.12 for electroweak $WWjj$ production. These contributions are modelled at LO but a NLO QCD $k$-factor of 1.7 is applied for gluon induced production. Theoretical predictions are indicated as markers with vertical lines denoting PDF, scale and parton shower uncertainties. Markers are staggered for better visibility.
