Searches for leptoquarks and heavy leptons with the ATLAS detector at the LHC

Leptoquarks are hypothetical particles predicted by extensions of the Standard Model, providing an explanation for the similarity between the quark and lepton sectors. Pair-produced scalar leptoquarks have been searched for using final states including leptons and jets. Similar final states are predicted in decays of heavy leptons/neutrinos including Type III neutral/charged leptons as well as heavy Majorana neutrinos produced in decays of heavy right-handed W or SM W boson. In this talk, recent ATLAS results on searches for Leptoquarks and heavy leptons with similar signatures using LHC Run 1 data are presented. First LHC Run-2 results will be included if available.
