Preliminary results on standard model processes in $e^{+}e^{-}$ collisions at 189 GeV

Very Preliminary Results on Fermion Pair Production in e+e- Collisions at 189 GeV and Resulting Limits on New Physics. Using data collected since May 1998, by the ALEPH detector in e+e- collisions at the LEP collider, very preliminary results on fermion pair production at a centre-of-mass energies of 189 GeV are presented. These results are used to place limits on new physics such as four-fermion contact interactions.
