Heavy long-lived charged particles crossing the CMS muon chambers in several bunch crossings are searched for using 3.7 fb−1 of data collected in 2024 at a center-of-mass energy of 13.6 TeV. The search relies on a new data set, so called Level-1 Scouting, collected without any trigger selection, allowing for correlations between bunch crossings to be analyzed. This analysis complements existing searches for heavy long-lived charged particles by extending the sensitivity to lower beta values.
