"63. MDS Run 2, Run 3 acceptance comparison" of "Strategy and performance of the CMS long-lived particle trigger program in proton-proton collisions at $\sqrt{s}$ = 13.6 TeV"

Comparison of the acceptances in Run 2 and Run 3 for the CSC (left) and DT (right) MDS triggers at the L1T and HLT as functions of the LLP lifetime, for $H \to S S \to b\bar{{b}}\,b\bar{{b}}$ events with $m_{H}=125$ GeV and $m_{S}=40$ GeV, for 2023 conditions. The acceptance is defined as the fraction of events that pass the specified selection, given an LLP decay in the fiducial region of the CSCs (left) or DTs (right). The left plot compares the acceptance of the Run 2 strategy of triggering on $p_T^{miss}$ (blue circles), which corresponds to an offline requirement of $>200$ GeV, with that of the Run 3 strategy of triggering on the MDS signature in the CSCs, for both the L1T (L1T+HLT) acceptance is shown with orange squares (red triangles). The right plot compares the acceptance of the Run 2 strategy of triggering on $p_T^{miss}$ (blue circles) with the Run 3 strategy of triggering on the MDS signature in the DTs (red triangles), for L1T+HLT.
