"22. L1T efficiency of LLP-flagged jets vs L1 jet ET [GeV]" of "Strategy and performance of the CMS long-lived particle trigger program in proton-proton collisions at $\sqrt{s}$ = 13.6 TeV"

The L1T efficiency of the LLP jet trigger in 2023 HCAL timing-scan data. The HCAL LLP-flagged L1T trigger delayed jet fraction versus jet $E_T$ during the 2023 HCAL phase scan demonstrates that the delayed jet fraction approaches unity as the timing shift increases. The results are inclusive in pseudorapidity for the HCAL barrel, corresponding to $|{\eta}| < 1.35$. The fraction of LLP-flagged L1 jets is compared to all L1 jets from a data set of events enriched with jets or $p_T^{\text{miss}}$. No explicit selection criterion is applied on the jet $E_T$, though the implicit requirement for a jet to have at least two cells with $E_T > 4$ GeV shapes the resulting jet trigger efficiency curve.
