Underlying Event Measurements Using CMS Detector at LHC

Results of recent underlying event (UE) measurements using data collected by CMS detector are presented. UE measurements are done using events containing a leading charged particle jet, a leading charged particle, a Drell-Yan (DY) lepton pair, and a \(t\bar{t}\) pair. Measurements are corrected to remove detector effect and are compared to various Monte Carlo (MC) predictions.
