# Measurement and interpretation of fermion-pair production at LEP energies of 183 and 189 GeV

Abstract : An analysis of the data collected in 1997 and 1998 with the DELPHIdetector at $e^+e^-$ collision energies close to 183 and 189GeV was performed in order to extract the hadronic and leptonic fermion--paircross--sections, as well as the leptonic forward--backward asymmetries andangular distributions.The data are used to put limit on contact interactions between fermions,the exchange of R-parity violating SUSY sneutrinos, $\Zprime$ bosons and the existence of gravity in extra dimensions.
