Abstract The performance of muon tracking, identification, triggering, momentum resolution, and scale has been studied with the CMS detector at LHC using data collected √( s NN ) = 5.02 TeV in proton-proton (pp) lead-lead (PbPb) collisions 2017 2018, respectively, 8.16 proton-lead (pPb) 2016. Muon efficiencies, resolutions, scales are compared by focusing on how reconstruction varies from relatively small occupancy pp to larger occupancies pPb and, finally, highest track multiplicity PbPb...

CMS Higgs boson Tau leptonA measurement of the production cross section a with transverse momentum greater than 250 GeV is presented where decays to pair τ leptons.It based on proton-proton collision data collected by experiment at CERN LHC center-of-mass energy 13 TeV.The sample corresponds an integrated luminosity 138 fb -1 .Because large leptons from its are boosted and produced spatially close, their decay products overlapping.Therefore, dedicated algorithm was developed reconstruct...
Abstract The Compact Muon Solenoid (CMS) experiment will undergo phase-II upgrade to enhance the capacity of detectors in High-Luminosity Large Hadron Collider era. An important extension involves installation Improved Resistive Plate Chambers (iRPC) most forward part endcap muon system. iRPC detector addresses efficiency drop experienced by current CMS trigger system for single triggers high pseudorapidity region. It features a double-ended read-out method, allowing determination hit...
