A Search for Vector-Like Leptons: Compact Analysis

The Standard Model (SM) conveys our fundamental understanding of matter and its interactions in the universe, yet within the current Standard Model, there remain unresolved questions. Theoretical extensions of the Standard Model are being developed in hopes to resolve these conflicts. Several SM extensions predict the existence of a new type of particle, the vector-like lepton (VLL). In a proposed search for vector-like leptons, we make use of data produced by proton-proton collisions at the Large Hadron Collider and collected by the Compact Muon Solenoid (CMS). This analysis focuses the search for pair-produced vector-like leptons with two SM leptons in the final state. Various SM processes exist that have a similar final state, a few being ttbar production, DY+jets, Di-boson production. This analysis examines several kinematic variables to explore distinctive characteristics between signal and background with the intention to search for the absence or presence of vector-like lepton signal by analyzing Run II data. Finally, limits will be set on vector-like lepton experimental parameters.
