Performance of jets and missing transverse momentum reconstruction at the High Level Trigger using Run 3 data from the CMS Experiment at CERN

Performance of the high-level trigger (HLT) algorithms involving jets and missing transverse momentum ($p_T^{miss}$) are studied using data collected in 2022, corresponding to an integrated luminosity of 34.3 $fb^{-1}$. The analyzed proton-proton (pp) collision dataset, which corresponds to a center of mass energy of $\sqrt{s} = 13.6$ TeV, is recorded using orthogonal isolated single muon triggers. The efficiency of the HLT triggers, which correspond to the fraction of events passing the trigger algorithm in question, are presented here as a function of the transverse momentum of the corresponding object reconstructed offline. The efficiencies are shown for before and after the hadronic calorimeter (HCAL) calibration update, also with and without the residual jet energy corrections applied on offline jets, which are used to correct for the calibration of the HCAL. For $p_T^{miss}$ triggers, the dependence of efficiency to the number of offline reconstructed primary vertices is also shown, as a gauge of pileup (PU) dependency of these triggers.
