Abstract
If quarks and leptons are composite at the energy scale , the strong forces binding their constituents induce flavor-diagonal contact interactions, which have significant effects at reaction energies well below . Consideration of their effect on Bhabha scattering produces a new, stronger bound on the scale of electron compositeness: GeV. Collider experiments now being planned will be sensitive to TeV for both electrons and light quarks.
