We study the resonance production of color octet leptons l₈ predicted by composite preon models of leptons and quarks at lepton-hadron colliders such as TESLA x HERA, p and Linac-LHC with the energy of about 1-10 TeV. The numerical results for l₈ cross sections are obtained from s and t channel diagrams. We also give the discovery contour for l₈ production in the k X M₋䃘 plane at these machines.
M. Kantar (Wed,) studied this question.
