Technicolor, Compositeness and GUT-based models are rich in high-pt leptons and could be studied in such final states. This contribution shows studies that indicate that a 5sigma discovery of a 500 GeV leptoquark could occur with 100 pb^-1 of integrated luminosity, Technicolor predicted particles could be seen with 4 fb^-1 of integrated luminosity and, excited electron could be detected with 300 fb^-1 of integrated luminosity.Proceedings submitted to 34th International Conference on High Energy Physics, Philadelphia, Pennsylvania, July 30-August 5, 2008. 4 pages, 5 figuresHigh Energy Physics - ExperimentSearch for Leptoquarks, Excited Leptons and Technicolor at the LHCtext
