Abstract

CMS experiment is collecting data on proton–proton collisions at the centre-of-mass energy of 13.6 TeV in LHC Run 3. The RPC detector is one of the sub-detectors of the CMS muon system which is capable of triggering and reconstructing muons. In this paper, efficiency of the CMS RPC detector during the Run 3 data taking period is presented. The Tag-and-Probe method with the decay of the Z boson to two muons was used in measuring the efficiency of the operating RPC detector. The efficiency is derived from the matching of RPC hits with probe muons extrapolated to the RPC.
