Acceptance times efficiency ($A \times \epsilon$) for three representative signal benchmark models from higgsino pair production with $L$-violating $\lambda'_{211}$ decays, overlaid with the observed event yields in data at each stage of the selection. The cut flow splits into two panels towards the right to present the $\text{SR}_{\mathrm{far}}$ and $\text{SR}_{\mathrm{near}}$ selections separately. The left-hand vertical axis shows $A \times \epsilon$ for the signal models, highlighting the complementarity of the two signal regions depending on the lifetime. Values of up to 38% are reached for proper lifetimes around 0.1 ns in the $\text{SR}_{\mathrm{far}}$ region, while the $\text{SR}_{\mathrm{near}}$ region provides additional sensitivity for shorter lifetimes. The right-hand vertical axis shows the observed event yields in data at each stage of the selection. The data yields are annotated on the plot.
