Searches for vector-like leptons in ATLAS

Vector-like leptons (VLLs) are among the simplest extensions of the Standard Model, with masses near the TeV scale. Depending on the assumed 𝑆𝑈(2) representation, VLLs can appear either as an 𝑆𝑈(2) doublet or singlet in the model. The latest results on searches for VLLs from the ATLAS Collaboration are presented in this talk, probing final states with multiple leptons, jets, and missing transverse energy. No evidence for new physics is observed and 95% confidence level limits are placed on the mass of vector-like electrons and muons appearing as 𝑆𝑈(2) singlets and vector-like taus appearing as 𝑆𝑈(2) doublets.
