Description:
We present a search for anomalous production of events with three or more isolated leptons produced in pp collisions at at the LHC. We analyze 2.1 fb−1 of data collected by the CMS experiment during the 2011 LHC run. The search is applicable to any model of new physics that produces multiple leptons. We categorize observed multilepton events into exclusive search channels based on the identity and kinematics of the objects in the events and ordered by the amount of expected standard-model background. We emphasize a data-based estimation of the standard-model backgrounds but also use simulation to estimate some of the backgrounds when appropriate. We interpret search results in the context of R-parity-violating models, for which the presence of missing transverse energy is not guaranteed due to the absence of stable supersymmetric particles. We derive exclusion limits as a function of squark and gluino masses for several R-parity- violating couplings.
