Searches for Compositeness in LEP

Resonant masses for excited fermions have been searched for by all the LEP collaborations. No signals have been found at LEP I or at 130-140GeV centre of mass energy. Pair produced excited fermions are excluded close to the kinematic limit Ebeam for leptons at the higher energy, and for quarks up to mz / 2. New limits have been set on the couplings required for the single production of excited fermions, up to the corresponding kinematic limit close to 2Ebeam.
