description: The ECAL time delay of the $\mathrm{e/\gamma}$ L1 seeds in the barrel. The distributions are shown for $\mathrm{Z\ \rightarrow\ ee}$ simulation and $\mathrm{\chi^{0}\ c\tau}$ values of $\mathrm{3\ cm,\ 30\ cm}$ and $\mathrm{3\ m}$, assuming the singlet-triplet Higgs dark portal model ($\mathrm{\chi^{\pm}\ \rightarrow\ \chi^{0} \ell^{\pm} \nu}$, where the $\mathrm{\chi^{\pm}}$ has a mass of $\mathrm{220\ GeV}$ and the $\mathrm{\chi^{0}}$ has a mass of $\mathrm{200\ GeV}$), for 2023 conditions. The distributions are normalized to unity.

title: "32.a. Delayed Di-Photon HLT rate. with intergated luminosity" of "Strategy and performance of the CMS long-lived particle trigger program in proton-proton collisions at $\sqrt{s}$ = 13.6 TeV"

description: The HLT rate (blue points) of the delayed-diphoton trigger for a few representative runs in the first data collected in 2023, corresponding to an integrated luminosity of $\mathrm{4.2\ fb^{-1}}$, compared with the PU during the same data-taking period (red points), as a function of integrated luminosity. The rate decreases nonlinearly during a single fill as a result of the increasing crystal opacity. It recovers by the start of the next fill with $\mathrm{&lt;\ 1\%}$ reduction in rate between the fills. The rate generally increased throughout the year because of periodic online calibrations to mitigate the loss in trigger efficiency, which was produced as a result of the ECAL crystal radiation damage. For display purposes in this HepData record, the PU value is scaled by 1/9.04.
