Track reconstruction efficiencies as a function of the muon ID track transverse impact parameter ($|d_0|$) for muons that originate from the decay of the higgsino. The primary, large-impact parameter (LRT), and combined tracking efficiencies are shown separately. Large-impact parameter tracking dominates the efficiency for $|d_0| > 5\,\text{mm}$. The benchmark sample used consists of higgsino pair-production events with $L$-violating $\lambda'_{211}$ decays ($m=200\,\text{GeV}$, $\tau=0.1\,\text{ns}$).
