Abstract
Contact interactions are searched for using the differential cross sec tions for the reactions e+e- --> e+e-, e+e- --> mu+mu-, e+e- --> tau+t au- and e+e --> gammagamma measured at 12 energies around the Z peak a nd corresponding to about 20 pb-1 of cumulated luminosity. Four-fermio n contact term models assuming various chiralities of lepton currents are fitted to the lepton data and lower limits on the energy scale LAM BDA 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 eegamm agamma contact terms are searched for assuming various chiralities. Li mits on the energy scale LAMBDA between 79 and 130 GeV are extracted f rom the data. The results are compared and combined with those reporte d at lower energies.
