The HLT efficiency, defined as the fraction of events recorded by the Run 2 (2018) triggers that also satisfied the requirements of the Run 3 (2022, L3) triggers, as a function of offline-reconstructed min($d_0$) of the two muons forming TMS-TMS dimuons in events enriched in J/ψ → μμ. The data represent efficiencies during the 2022 and 2023 data-taking periods. For dimuons with offline min($d_0$) > 0.012 cm, the combined efficiency of the L3 muon reconstruction and the online min($d_0$) requirement is larger than 90% in all data-taking periods.
