title: "Table 22" of "Search for a new Z' gauge boson in $4\mu$ events with the ATLAS experiment"

description: Kinematic distributions of the pre-selected $4\mu$ events. The plots (a) to (d) are the $\eta$ distributions of the 4 muons ($p_{T}$ ordered). In addition to the major background from the SM $Z(Z^*)\rightarrow 4\mu$ production, other backgrounds, including 4$\mu$ events containing non-prompt muons estimated from data, and from $ttV$, $VVV$, and Higgs boson production processes, are included in the plots. Examples of the Z' signal from $pp\rightarrow Z'\mu^+\mu^- \rightarrow 4\mu$ process with masses of 15 and 51 GeV are also shown in the plots.
description: This paper presents a search for a new $Z'$ vector gauge boson with the ATLAS experiment at the Large Hadron Collider using $pp$ collision data collected at $\sqrt{s} = 13$ TeV, corresponding to an integrated luminosity of 139 fb$^{-1}$.The new gauge boson $Z'$ is predicted by $L_{\mu}-L_{\tau}$ models to address observed phenomena that can not be explained by the Standard Model.The search examines the four-muon (4$\mu$) final state, using a deep learning neural network classifier to separate the $Z'$ signal from the Standard Model background events.The di-muon invariant masses in the $4\mu$ events are used to extract the $Z'$ resonance signature.No significant excess of events is observed over the predicted background.Upper limits at a 95% confidence level on the $Z'$ production cross-section times the decay branching fraction of $pp \rightarrow Z'\mu\mu \rightarrow 4\mu$ are set from 0.31 to 4.3 fb for the $Z'$ mass ranging from 5 to 81 GeV.The corresponding common coupling strengths, $g_{Z'}$, of the $Z'$ boson to the second and third generation leptons above 0.003 -- 0.2 have been excluded.

description: Distribution of $H_T / p_{T}^{\mu_{1}}$ for signals, backgrounds and data. The bins are used in the simultaneous fit. The bins 1-4 show the events in the high-$\Delta\Phi_{ll}$ signal region (SR), the bins 5-7 show the events in the low-$\Delta\Phi_{ll}$ SR, the bins 8-11 show the events in the low-$p_T^{miss}$ SR, the bins 12-15 show the events in the high-$p_T^{miss}$ SR, the bins 16-19 show the events in the b-tagged control region (CR), the bins 20-23 show the events in the high-$\Delta\Phi_{ll}$ and $p_T^{miss}$ CR, and the bins 24-26 show the events in the WZ CR, and the bins 31-33 show the events in the WZb CR. The predicted background yields are shown with their best fit normalizations from the simultaneous fit for the signal+background hypothesis. The signal yields are their expected yields from simulation, which are scaled by the some fators as from the plots. Vertical bars on data points represent the statistical uncertainty in the data. Vertical bars on total backgrounds represent the statistical+systematic uncertainties. Vertical bars on the signals represent the statistical+systematic uncertainties. The histograms for TVX backgrounds include the contributions from ttV and tZq processes. The histograms for other backgrounds include the contributions from double parton scattering, VVV. The overflow is included in the last bin in each corresponding region.
description: The first search exploiting the vector boson fusion process to probe heavy Majorana neutrinos and the Weinberg operator at the LHC is presented. The search is performed in the same-sign dimuon final state using a proton-proton collision data set recorded at $\sqrt{s}=13$ TeV, collected with the CMS detector and corresponding to a total integrated luminosity of 138 $\text{fb}^{-1}$. The results are found to agree with the predictions of the standard model. For heavy Majorana neutrinos, constraints on the squared mixing element between the muon and the heavy neutrino are derived in the heavy neutrino mass range $50$ GeV -- $25$ TeV; for masses above 650\GeV these are the most stringent constraints from searches at the LHC to date. A first test of the Weinberg operator at colliders provides an observed upper limit at 95\% confidence level on the effective $\mu\mu$ Majorana neutrino mass is $10.8$ GeV.
