Searching for Color Octet Leptons in Lepton-Hadron Collisions

Abstract

We study the resonance production of color octet leptons ${l_8}$ predicted by composite preon models of leptons and quarks at lepton-hadron colliders such as TESLA x HERA,$\mu p$ and Linac-LHC with the energy of about 1-10 TeV. The numerical results for ${l_8}$ cross sections are obtained from s and t channel diagrams. We also give the discovery contour for ${l_8}$ production in the ${k} X M_{l_8}$ plane at these machines.
