The High Multiplicity Trigger paper is published in JINST

Our paper High Multiplicity Trigger for Long-Lived Particles in CMS Detector is published in JINST. The paper presents a dedicated trigger that targets unusually large hit multiplicities in the CMS muon detectors, a characteristic signature of long-lived particles decaying in the muon system, substantially extending the CMS sensitivity to such signatures during LHC Run 3. I contributed the electron+MDS and muon+MDS cross triggers, which were accepted into the CMS trigger menu in 2023.
