摘　　要：Limits on contact interactions If quarks and leptons are made of constituents, then at the scale of constituent binding energies there should appear new interactions among them. At energies much below the compositeness scale （∧）, these interactions are suppressed by inverse powers of A. The dominant effect of the compositeness of fermion φ should come from the lowest dimensional interactions with four fermions （contact terms）,Limits on contact interactions If quarks and leptons are made of constituents, then at the scale of constituent binding energies there should appear new interactions among them.
