Upper limits (95% CL) from the DV+jets channel on the production cross-section and the corresponding event-level efficiencies (from Auxiliary Figure 10b) for four split-SUSY models as a function of the $\tilde{g}$ proper decay distance $c\tau$. The models consider gluino pair production, with $[\tilde{g}\to g/qq \tilde{\chi}_1^0]$ decays, $\tilde{g}$ masses in GeV as indicated and $m(\tilde{\chi}_1^0)$ = 100 GeV. For comparison, the production cross-sections for $m(\tilde{g})$ = 400 GeV, 800 GeV and 1400 GeV are $18700\pm2800$ fb, $149\pm31$ fb and $0.71\pm0.32$ fb, respectively. A dash indicates where the limit-setting procedure did not converge or the limit is greater than $10^8$ fb.

Upper limits (95% CL) from the dilepton $e^{\pm}\mu^{\mp}+\mu^+\mu^-$ channels on the production cross-section and the corresponding event-level efficiencies (from Auxiliary Figure 6b) for four RPV SUSY models as a function of the $\tilde{\chi}_1^0$ proper decay distance $c\tau$. The models consider gluino pair production, with $\tilde{g}\to qq[\tilde{\chi}_1^0\to e\mu\nu/\mu\mu\nu]$ decays and masses in GeV as indicated. For comparison, the production cross-sections for $m(\tilde{g})$ = 600 GeV and 1300 GeV are $1280\pm230$ fb and $1.7\pm0.7$ fb, respectively. A dash indicates results omitted due to limited statistical precision.

Upper limits (95% CL) from the DV+jets channel on the production cross-section and the corresponding event-level efficiencies (from Auxiliary Figure 8b) for four RPV SUSY models as a function of the $\tilde{\chi}_1^0$ proper decay distance $c\tau$. The models consider squark pair production, with $\tilde{q}\to q\tilde{\chi}_1^0$ decays, $m(\tilde{q})$ = 1000 GeV and $m(\tilde{\chi}_1^0)$ = 108 GeV. For comparison, the production cross-section for $m(\tilde{q})$ = 1000 GeV is $11.9\pm1.5$ fb. A dash indicates where the limit-setting procedure did not converge.

Upper limits (95% CL) from the DV+jets channel on the production cross-section and the corresponding event-level efficiencies (from Auxiliary Figure 8a) for four RPV SUSY models as a function of the $\tilde{\chi}_1^0$ proper decay distance $c\tau$. The models consider squark pair production, with $\tilde{q}\to q\tilde{\chi}_1^0$ decays, $m(\tilde{q})$ = 700 GeV and $m(\tilde{\chi}_1^0)$ = 494 GeV. For comparison, the production cross-section for $m(\tilde{q})$ = 700 GeV is $124\pm17$ fb. A dash indicates where the limit-setting procedure did not converge.

Upper limits (95% CL) from the DV+$E_T^{miss}$ channel on the production cross-section and the corresponding event-level efficiencies (from Auxiliary Figure 11a) for four RPV SUSY models as a function of the $\tilde{\chi}_1^0$ proper decay distance $c\tau$. The models consider squark or gluino pair production, with masses in GeV as indicated, with either $\tilde{q}\to q[\tilde{\chi}_1^0\to \nu qq]$ or $\tilde{g}\to qq[\tilde{\chi}_1^0\to \nu qq]$ decays, respectively. For comparison, the production cross-sections for $m(\tilde{g})$ = 700 GeV, $m(\tilde{q})$ = 700 GeV and $m(\tilde{q})$ = 1000 GeV are $430\pm80$ fb, $124\pm17$ fb and $11.9\pm1.5$ fb, respectively.

The measured fiducial cross sections are corrected to the dressed level. The ratio of $C_{WZ}^{\textrm{dressed}}/C_{WZ}^{\textrm{Born}}$ factors presented in this table can be used to correct fiducial integrated cross sections from dressed to Born level.

Observed and expected upper limits at $95\%$ CL in fb on the fiducial cross section $\sigma^{\mathrm{fid.}}_{W^{\pm} Zjj \textrm{-EW} \rightarrow \ell^{'} \nu \ell \ell}$, multiplied by the $W$ and $Z$ branching ratios in a single leptonic channel with muons or electrons in the VBS fiducial phase space. Values obtained with or without subtraction of the $tZj$ contribution are presented. The $1$ $\sigma$ and $2$ $\sigma$ uncertainty intervals around the expected limits are also indicated.
