Comparison of different the dijet mass $m_{\text{J}\text{J}}$, the transverse mass $m_{\text{T}}$, and the Monte Carlo (MC) mass $m_{\text{MC}}$ for a signal model with $m_{\text{Z}^{\prime}} = 2.1\,\text{TeV}$, $m_{\text{dark}} = 20\,\text{GeV}$, $r_{\text{inv}} = 0.3$, $\alpha_{\text{dark}} = \alpha_{\text{dark}}^{\text{peak}}$. No selection is applied, except that there must be at least two jets. $m_{\text{MC}}$ is computed by adding the generator-level four-vectors for invisible particles to the dijet system, to represent the achievable resolution if the invisible component were fully measured. The last bin of each histogram includes the overflow events.

Inclusive ttbar cross section in pp collisions as a function of the center-of-mass energy; previous CMS measurements at 7, 8, and 13 TeV in the separate lepton+jets and dilepton channels are displayed, along with the combined measurement at 5.02 TeV presented in this analysis. The NNLO+NNLL theoretical prediction using the NNPDF3.1 PDF set with $alpha_{S}({m}_{Z})$ = 0.118 and ${m}_{t}$ = 172.5 GeV is shown in the main plot. In the inset, the combined measurement is shown together with previous measurements at 5.02 TeV, and additional predictions at 5.02 TeV using the MSHT20 , CT18, and ABMP16 NNLO PDF sets, the latter with $alpha_{S}({m}_{Z})$ = 0.115 and ${m}_{t}$ = 170.4 GeV, are compared, along with the NNPDF3.1 NNLO prediction, to the individual and combined results from this analysis. The vertical bars and bands represent the total uncertainties in the data and in the predictions, respectively. Points corresponding to measurements at the same center-of-mass energy are horizontally shifted for better readability.

Signal yields following each cut in the analysis, for representative $R$-parity-violating supersymmetry and leptoquark signals. All yields are MC generator-weighted and normalised to $139~\text{fb}^{-1}$. The cut labelled `Preselection' includes trigger requirements, and requires exactly one Baseline electron and one Baseline muon. At this point, the muon charge-bias correction weights are also applied. The $R$-parity-violating supersymmetry models were generated by specifying a top-quark in the final state and applying a two-lepton filter, hence the first row also includes events where the top quark decays to an electron.
