| Abstract: 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, for the first time, on the Level-1 Scouting data set, collected without any trigger selection, allowing for correlations between bunch crossings to be analyzed. The results are interpreted as upper limits on the production cross section of several benchmark processes with pair-production of heavy long-lived charged particles. Fiducial upper limits on the cross section of a heavy long-lived charged particle with $ p_T > $ 500 GeV and $ |\eta| < $ 0.83 are also set in different ranges of $ \beta=v/c $. This analysis is a crucial proof-of-concept of the Level-1 Data Scouting system and complements existing searches for heavy long-lived charged particles by extending the sensitivity to lower $ \beta $ values. | ||
