Abstract:
I will describe the CMS search for anamolous production of multilepton events. This is a broad search with numerous integrated "search" and "control" channels that parses the events in terms of their characteristics such as number of leptons, number of tau leptons, missing energy, hadronic energy, effective mass, presence of Drell-Yan lepton pairs, invariant masses on-Z or off-Z and so on. The search has hit upon several surprising finds with LHC-wide impact. I will also present the findings in terms of SUSY R-parity conserving as well as violating models and a simple model of electroweak production.
