Searches for new physics with leptons in ATLAS

Leptonic final states are rare and have relatively small backgrounds at a hadron collider. Many models of beyond the Standard Model physics predict new particles which may decay into high pt leptons and/or anomalously large missing transverse energy. A number of exotic signatures, such as W', Z', SUSY, Leptoquarks, LRSM Majorana neutrinos and diboson resonances, are being searched for by ATLAS. The prospects and results of some of these searches with the early data collected by ATLAS in 2010, are presented here.
