Trigger efficiency studies of the CMS Run-3 Data Scouting of Jet, Electron and Photon objects and comparison with standard HLT paths during during proton-proton collisions at $\sqrt{s}$ = 13.6 TeV
The trigger performance of the data scouting strategy used by the CMS experiment in Run-3 is studied by analysing the proton-proton collision dataset, having centre of mass energy of 13.6~TeV with a total integrated luminosity of 34~fb$^{-1}$ in 2022, 10~fb$^{-1}$ at the beginning of 2023 and 27~fb$...

Sumario: | The trigger performance of the data scouting strategy used by the CMS experiment in Run-3 is studied by analysing the proton-proton collision dataset, having centre of mass energy of 13.6~TeV with a total integrated luminosity of 34~fb$^{-1}$ in 2022, 10~fb$^{-1}$ at the beginning of 2023 and 27~fb$^{-1}$ for all of 2023. The efficiency distributions for the data scouting jets, electrons and photons as a function of their offline reconstructed counterparts are shown. Data scouting is fully efficient for AK4 jets with transverse momenta ($p_T$) approximately $>$~300~GeV, for AK8 jets with $p_T >$~300~GeV and for scalar sum of transverse energy ($H_T$)~$>$~400~GeV. A comparison with the standard High-Level Trigger (HLT) strategy shows that data scouting is more efficient at selecting low energy jets. In addition to the jet trigger efficiency studies performed with recorded data, a study performed with simulated data shows higher trigger efficiency for data scouting compared to the standard HLT selection of Higgs bosons produced with high transverse momentum decaying into a bottom quark-antiquark pair.
The efficiency studies performed with recorded data further shows that electrons and photons in data scouting are sensitive to physics above $p_T >$~30~GeV in scenarios where one electron or photon is required. |
