Contact interactions are searched for using the differential cross sections for the reactions e + e -\u2192 e + e -, e + e -\u2192 \ub5 + \ub5 -, e + e -\u2192 \u3c4 + \u3c4 - and e + e -\u2192\u3b3\u3b3 measured at 12 energies around the Z peak and corresponding to about 20 pb-1 of cumulated luminosity. Four-fermion contact term models assuming various chiralities of lepton currents are fitted to the lepton data and lower limits on the energy scale \u39b of such terms are set at 95% c.l. The limits vary in the range 0.9 4.7 TeV, depending on the model and on the lepton flavour. The ee\u3b3\u3b3 contact terms are searched for assuming various chiralities. Limits on the energy scale \u39b between 79 and 130 GeV are extracted from the data. T...
