2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/44874We discuss the production of heavy leptons at a future high--energy $e^+e^-$ linear collider with a center of mass energy of 500 GeV. Signals and backgrounds are analyzed for their single production in association with ordinary leptons.
