Comparison of distributions for the displaced-jet tagging variables $\alpha_{\text{max}}$ (left), $\widehat{\mathrm{IP}}{}^{\mathrm{2D}}_{\text{sig}}$ (center), and $\widehat{\Theta}_{\mathrm{2D}}$ (right) in data and simulation. The data distributions (circles) are compared to the expected background distributions from multijet events (squares) and several Jet-Jet benchmark models (dotted histograms) of pair-produced long-lived neutral scalar particles with $m_{X^{0}} = 700 \GeV$ and different values of $c\tau_0$. The vertical lines designate the value of the requirement for the chosen displaced-jet tag. The direction of the arrow indicates the values included in the requirement. All distributions have unit normalization.

The fraction of jets passing the displaced-jet tagging criteria as a function of the number of tracks associated with the jet. The results are from data events with $N_{\text{tags}} \leq 1$, collected with the displaced-jet triggers and passing the offline selection criteria.

The excluded cross section at 95\% CL for the Jet-Jet model (upper left) and the B-Lepton model (upper right) as a function of the mass and proper decay length of the parent particle. The B-Lepton plot also shows the expected (observed) exclusion region with one standard deviation experimental (theoretical) uncertainties, utilizing a NLO+NLL calculation of the top squark production cross section. The lower plot shows the excluded cross section at 95\% CL for the Jet-Jet model as a function of the proper decay length for three illustrative smaller values of the mass. The shaded bands in the lower plot represent the one standard deviation uncertainties in the expected limits.
