"25.a. HLT efficiency of CalRatio trigger vs. leading jet NHEF" of "Strategy and performance of the CMS long-lived particle trigger program in proton-proton collisions at $\sqrt{s}$ = 13.6 TeV"

The HLT efficiency of the CalRatio trigger as a function of the leading PF jet NHEF in 2024 data, measured with respect to a logical OR of the HCAL-based LLP L1 jet triggers (left). Events are required to have $H_{\mathrm{T}} > 200 \,\mathrm{GeV}$ and the leading jet is required to have $p_{\mathrm{T}} > 60 \,\mathrm{GeV}$ and $|\eta| < 1.5$, which are equivalent to the respective HLT jet object selections. The signal distributions additionally require the leading jet to be matched to an LLP decaying anywhere inside the barrel calorimeter volume ($129 < R < 295 \,\mathrm{cm}$).
